Account requests are now handled via this link: Special:RequestAccount (wiki)
So the wiki had some really bad database corruption, and since we were pretty much hosed, we reset most of the databases. This means all user accounts on the wiki have been reset. They technically don't exist, but they still have "history", meaning they just need to be re-registered. I'm very sorry about the inconvenience, but this is was the best course of action to get the wiki up and running again fast, and to correct some deep issues it was having.
So what does this mean now? I'm not sure. I'm still restoring the wiki, and I'll know more by tomorrow.
Account creation on the wiki has been temporarily disabled until the wiki is switched to an OpenID login system. If you need an account before then, please request one here.
If you've already made an account on the wiki, that will still work. You do not need an account to read the wiki. If you just need something changed real quick and don't plan on doing a lot of editing, etc, feel free to message me with the requested change.
UPDATE (2013-7-5): I'm not sure how much longer it will be for OpenID to work, or some alternative log-in system. We discovered that there's an incompatibility with the server software and the requirements for OpenID, but since that server also needs some updates, it's possible that incompatibility will be resolved. I just don't know how long it will take.
