Some wiki engines offer a blacklist feature which prevents users from adding hyperlinks to specific sites that have been placed on the list by the wiki’s administrators. Wiki implementations retaining and allowing access to specific versions of articles has been useful to the scientific community, by allowing expert peer reviewers to provide links to trusted version of articles which they have analyzed. For example, in 2006 a German Wikipedia article about the Blaster Worm was edited to include a hyperlink to a malicious website, and users of vulnerable Microsoft Windows systems who followed the link had their systems infected with the worm. Some wiki engines provide additional content control, allowing remote monitoring and management of a page or set of pages to maintain quality. Wiki administrators maintain content and, through having elevated privileges, are granted additional functions (including, for example, preventing edits to pages, deleting pages, changing users’ access rights, or blocking them from editing). In this concept of wiki federation, in which the same content can be hosted and edited in more than one location in a manner similar to distributed version control, the idea of a single discrete “wiki” no longer made sense.
Such a wiki contains information about specific instances of things, ideas, people and places. The term city wiki is sometimes also used for wikis that cover not just a city, but a small town or an entire region. A city wiki or local wiki is a wiki used as a knowledge base and social network for a specific geographical locale. In academic contexts, wikis have also been used as project collaboration and research support systems.

• Many other Wikipedias are available; some of the largest are listed below.
• Concerns have also been raised about systemic bias along gender, racial, political, corporate, institutional, and national lines.
• The list displays metadata for each revision to the page, such as the time and date of when it was stored, and the name of the person who created it, alongside a link to view that specific revision.

Some wiki implementations keep a record of changes made to wiki pages, and may store every version of the page permanently. WYSIWYG editors may not provide all the features available in wiki markup, and some users prefer not to use them, so a source editor will often be available simultaneously. The syntax and features of wiki markup languages for denoting style and structure can vary greatly among implementations.
In that implementation, link terms were wrapped in a double set of square brackets, for example Kingdom of France. To avoid this problem, the syntax of wiki markup gained free links (called wikilinks), wherein a term in natural language could be wrapped in special characters to turn it into a link without modifying it. For example, “Kingdom of France” as a page title would be written as “KingdomOfFrance”, and displayed as “Kingdom Of France”. Beginning with WikiWikiWeb in 1995, most wikis used camel case to name pages, which is when words in a phrase are capitalized and the spaces between them removed. The syntax used to create internal hyperlinks varies between wiki implementations.

• Some copyright issues can be alleviated through the use of an open content license.
• In contrast, articles on other languages’ Wikipedias often focus on regional issues.
• Some wiki engines offer a blacklist feature which prevents users from adding hyperlinks to specific sites that have been placed on the list by the wiki’s administrators.
• Wiki administrators maintain content and, through having elevated privileges, are granted additional functions (including, for example, preventing edits to pages, deleting pages, changing users’ access rights, or blocking them from editing).
• For the version of Wikipedia written in Basic English, see Simple English Wikipedia.
• Some wikis operate a structure of neighbors and delegates, where a neighbor wiki is one which discusses similar content or is otherwise of interest, and a delegate wiki is one which has agreed to have certain content delegated to it.
• While wiki engines have traditionally offered source editing to users, as early as 2013, some implementations have added a rich text editing mode.

The version history feature allows harmful changes to be reverted quickly and easily. Most wikis offer a recent changes page which shows recent edits, or a list of edits made within a given time frame. Some hosting services offer private, password-protected wikis requiring authentication to access. The software which powers a wiki may be implemented as a series of scripts which operate an existing web server, a standalone application server that runs on one or more web servers, or in the case of personal wikis, run as a standalone application on a single computer.

Navigation between wikis

Wikis may allow any person on the web to edit their content without having to register an account on the site first (anonymous editing), or royaldogs casino require registration as a condition of participation. Some wikis also implement patrolled revisions, in which editors with the requisite credentials can mark edits as being legitimate. A person willing to maintain pages will be alerted of modifications to them, allowing them to verify the validity of new editions quickly. System administrators are responsible for the installation and maintenance of the wiki engine and the container web server. Wikis can also be created on wiki hosting services (also known as wiki farms), where the server-side software is implemented by the wiki farm owner, and may do so at no charge in exchange for advertisements being displayed on the wiki’s pages. On March 15, 2007, the word wiki was listed in the online Oxford English Dictionary.
Some companies use wikis as their collaborative software and as a replacement for static intranets, and some schools and universities use wikis to enhance group learning. In the early 2000s, wikis were increasingly adopted in enterprise as collaborative software. Such links are usually differentiated visually in some fashion, such as being colored red instead of the default blue, which was the case in the original WikiWikiWeb, or by appearing as a question mark next to the linked words. This syntax was adopted by a number of later wiki engines.

The trend analysis published in The Economist presents Wikipedia in other languages (non-English Wikipedia) as successful in retaining their active editors on a renewable and sustained basis, with their numbers remaining relatively constant at approximately 42,000. The Economist reported that the number of contributors with an average of five or more edits per month was relatively constant since 2008 for Wikipedia in other languages at approximately 42,000 editors within narrow seasonal variances of about 2,000 editors up or down. These ideas include “featured articles”, the neutral-point-of-view policy, navigation templates, the sorting of short “stub” articles into sub-categories, dispute resolution mechanisms such as mediation and arbitration, and weekly collaborations. Editors of the English Wikipedia have pioneered some ideas as conventions, policies or features which were later adopted by Wikipedia editions in some of the other languages. The English Wikipedia currently has 54,334,804 registered accounts of which 811 are administrators. English Wikipedia has been characterized as having less cultural bias than other language editions due to its broader editor base.

WikiNode networks act as webrings which may be navigated from one node to another to find a wiki which addresses a specific subject. Adding categories or tags to a page makes it easier for other users to find it. Wiki implementations can provide one or more ways to categorize or tag pages to support the maintenance of such index pages, such as a backlink feature which displays all pages that link to a given page. Users may also create indexes or table of contents pages, hierarchical categorization via a taxonomy, or other forms of ad hoc content organization.
In the mid-2000s, the increasing trend among industries toward collaboration placed a heavier impetus upon educators to make students proficient in collaborative work, inspiring even greater interest in wikis being used in the classroom. In addition to using the approach of soft security for protecting themselves, larger wikis may employ sophisticated methods, such as bots that automatically identify and revert vandalism. “Edit war” redirects here; not to be confused with Edit conflict.
