Open registration of new accounts on the wiki is disabled for security purposes. Captchas have kept out spambots, but don't protect against malicious human editors, something we unfortunately have experienced in the past.
New users can get an account by asking in the Discussion thread, the chatroom, or by privately contacting a wiki sysop. Wiki sysops are the only people who can create new accounts. Note: when you get a new account, immediately change your password upon logging in the first time, as the initial password is manually set by the sysop creating the account..
