MediaWiki as a Successor to UseMod Edit

UseMod was originally what powered Wikipedia, and it's still in use on some wikis, the most popular being MeatballWiki. UseMod used CamelCase for links where MediaWiki uses brackets. MediaWiki also allows for usernames and infinite page histories, where UseMod only keeps page histories for 2 weeks and you can't "own" a username per se. MediaWiki also has extensions that allow the system administrator to improve and add features. A few wikis that were previously running UseMod upgraded to MediaWiki
