Edit: Posts by new users are disabled until we figure out how to deal with the spammers. We've had a substantial spam attack today - thanks to all moderators keeping the site clean. In response we have turned on mandatory email verification on all accounts. During log-in you will be asked to verify the email that is on your account.
