NOTE: New wiki account creation is currently disabled. If you need an account please email "nominolo" (at the email service from Google) or on the haskell-cafe mailing list.
In the email state your preferred username for the wiki. (Use Special:Listusers to check if the username is available). A wiki admin will then create an account for you and a temporary password will then be sent to your email address.
This is a temporary measure. We are looking into better solutions with a shorter account creation delay.
