Due to the rash of trolls joining recently, I've shifted the signup of new members to "manual activation".
This means after registering, a new user cannot start posting until I manually approve their account.
I will revert back to "self activation" once I've finished installing some phpBB mods which will prevent the trolls posting any of their links.
New members, please be patient, you should get activated within 12 hours at the most.
