Due to irreconcilable differences with Wikia, members of the WoWWiki community resolved in October 2010 that they would leave Wikia. Their preference at the time was to remove WoWWiki itself from the Wikia network, taking the domain and WoWWiki name with them, but this proved impossible, as Wikia policy is to not remove wikis from use when they leave. Instead, a fork was set up, and Curse offered to host it.
Wowpedia's initial database contained a complete copy of articles from WoWWiki as of 18 October 2010. Editing on both sites since that time and edits made in the future will further differentiate these sites from one another.
There are a number of differences, some imperceptible to the lay user. The most obvious are that, on Wowpedia, the sidebar is in its original place and it is not fixed width. Also, there were no ads on Wowpedia for the first two months of its creation, afterward having just a single, non-obtrusive banner ad at the top of every page. Many of the new 'social' features introduced by Wikia do not exist, such as Facebook Connect and avatars. Additionally, watchlists will remain private, which is contrary to Wikia's implementation of public followed lists.
The decision to move among WoWWiki's administrators was practically unanimous, minus Kirkburn (who is a Wikia staff member). Many members of the active user base transferred to Wowpedia within a week of Wowpedia opening. Other members of WoWWiki either stayed behind to continue on this site or resolved to contribute to both. Wikia has no plans to close WoWWiki and has been installing administrators to replace those that left, as well as starting giveaways in order to generate enthusiasm for its site.
During the transition phase, there was a controversy over WoWWiki admins leaving messages to people informing them about the new site. This issue has yet to be resolved.
Reclaiming your user name
Wowpedia contains a tool to 'reclaim' one's user name. All that needs to be done is to click on the 'Register' button and tell it your user name. The site will then generate a code; you can enter this code in an edit summary on your WoWWiki user page to confirm your identity. No edits made prior to 18 Octoboer 2010 are lost, as the entire history up to that point (including your user page and any subpages) is intact.
