Unfortunately we seem to have a bit of a problem with filthy spammers signing up for new accounts and then spamming the news posts and forums. Until we can work out how to prevent this then I have required that new user registrations require activation by an administrator before they can post.
Sorry for the inconvenience.
-P
[EDIT]Ok, ive attempted to block the main areas where the spammers have been coming from, so if the frequency of requests decrease over the next few days, user registration will be back to normal
