We'll be moving the wiki to its own subdomain in the next few days. MediaWiki requires some functions that are disabled in the forum software's instance of php out of concern for security. This will fix all of the issues the wiki has had as of late.
I'd also like to make everyone aware of how to register; you must send myself, Cory5412 Bunsen or ChristTrekker a private message to have an account created. Please include an email address, username and temporary password.
