All,
I've been forced to install a new forum, as the old one was being abused because it was insecure. Some hackers managed to hijack one of the forum scripts and used it to send around 20,000 emails, which didn't please my web hosts. The old forum has been removed, remedying the problem.
In changing the forum, I've managed to preserve all users and posts. The "look" of the forum is the default one, which I will modify to fit in with the rest of the site when I have time to do so. I sincerely apologise for any inconvenience this change may have caused.
Thank you for your continued support.
