Due to the recent problem with spambots, user registration will now require administrator validation. Once you register, please send an email to [email removed] containing your display name so that I know you are not a spambot, and I will validate your account.
Hopefully this is temporary. We should eventually be able to prevent bots from registering and posting on the forum at all.
For an example of how this has helped the forums, take a look at the list of validating members (link broken). These members have not been approved because they did not request validation.
UPDATE: This policy ended a long time ago. Please don't send me any more emails. Honestly, I hadn't checked that email account in nearly three years.
