MediaWiki is also used extensively, ''and'' exclusively by all other wiki sites hosted by the {{tag|Wikimedia Foundation}} (WMF) (including all of their wiki '{{WMF-Meta|Wikimedia projects|projects}}'); along with many, <u>many</u> other [[:Category:Independent|independently]]-hosted [[:Category:All|wiki sites]]. MediaWiki is also the software of first choice to power many different [[:Category:Free MediaWiki wiki farm|free]] and commercial [[:Category:MediaWiki wiki farm|large wikiswiki farms]].
MediaWiki is probably ;''History and featuresAfter it was discovered that the most widely deployed wiki [[:Category:UseMod Wiki|UseMod Wiki]] software. Some would argue that was not adequate nor appropriate to power a wiki should be more simplistic-based [[:Category:Encyclopedia|encyclopedia]], with fewer featuresa new software solution was required for [[:Category:Wikipedia|Wikipedia]]. The initial 'pre-version' software (known as 'Phase II (2) software' in Wikipedia circles) was created by [[Magnus Manske]], but the design avoids many of and was used on all available Wikipedia versions from 25 January {{tag|Founded in 2002|2002}}. A 'Phase III (3) software' became the clutterfirst 'official' <u>'''MediaWiki'''</feature-creep problems appearing in other mature wiki enginesu> software, and its success speaks for itselfthis was a substantial re-write of Phase II by [[Lee Daniel Crocker]]; this new 'MediaWiki' software was first used on the [[English Wikipedia]] on 20 July 2002.
The following wikis are powered by MediaWiki is compiled and written in the {{tag|PHP}} programming language, and is probably one of the most widely deployed wiki engines in the global [[wikisphere]]. Some might argue that a [[WhatIsWiki|wiki]] should be more simplistic, with fewer features, and some have commented that MediaWiki has now become [[:Category:Bloatware|bloatware]];[https://getwiki.net/-GetWiki:Overview] however, MediaWikis'design,<!--avoids many of the clutter / feature–creep problems that can appear in other mature wiki engines--> and its prolific success speaks for itself. MediaWiki has spawned many {{Cambridge-Dictionary|clone}}s, or '[[:Category:Fork|forks]]', the most notable being [[:Category:Wikia|Wikia]] (now {{Cambridge-Dictionary|branded}} as Fandom), along with [[:Category:GetWiki|GetWiki]] (created for [[Wikinfo|Wikinfo.org]]). MediaWikiis extremely highly (and constantly) developed, it is feature-rich, {{tag|open source}}, and is now very complex {{tag|free software}}, that is released under version 2 of the {{tag|GNU General Public License}} (GNU GPL v2). MediaWiki requires either [[:Category:MySQL|MySQL 5.0.2+]], [[:Category:PostgreSQL|PostgreSQL]], or [[:Category:SQLite|SQLite]] for data storage; it can <u>not</u> use 'flat-file'' wiki enginedata storage.
In December [[:Category:Founded in 2008|2008]], a guy found [[Archive.org:20130121165457/http://CS.Brown.edu/~pavlo/mediawiki|all open installs]] ([[Archive.org]] link) of the MediaWiki code. And until mid-[[:Category:Founded in 2013|2013]], there used to be the [[Archive.org:20130508132829/http://MWusers.com/forums/forum.php|MediaWiki Users forums]] (Archive.org link). ;''MediaWiki [[:Category:Wiki Size|size]] information:add <tt>/Special:Statistics</tt> at the end of the URL – {{Cambridge-Dictionary|eg|e.g.}} <code><nowiki>https://YourWikiURL.org/wiki/Special:Statistics</nowiki></code> (non-English [[:Category:Wiki language|language]] interface versions will automatically convert this to their actual language). Dependent on MW software {{Mw|version}}, there is a number called 'Content pages', or on earlier MW versions 'pages that are probably legitimate content pages'; use <u>that</u> lower number.
