We've had a massive bot problem lately on the forums, with scrapers near-constantly pinging the server to the point where it's DDoSing the site. I've been playing whack-a-bot with their IPs but it's a losing battle. So unfortunately I've had to set the forums to user-only. Guests will no longer be allowed to read any of the forums.
If you wish to still read the forums, please register an account. You can use a throwaway email address if you want and don't even have to post. However, to keep the site accessible to humans and server costs down, this is something that has to happen. Apologies to all the actual guests affected.
