A guy on the Facebook group is trying to register but having problems. I thought I'd try to work out what's up but on the page for registering it just says the words “Hacking attemptâ€.
Is that a bug or really some kind of anti-hacking failsafe.
That happens if you try to access the old (pre quiz) registration page at https://www.adventuregamestudio.co.uk/forums/index.php?action=register, instead of https://www.adventuregamestudio.co.uk/forums/index.php?action=quiz. Google probably still has links to the old one. I've set it up now so it'll redirect people to the correct page automatically.
