We're currently getting a high number of application requests - 30 this morning alone - almost certainly because of the success of the bot the other day. Temporarily, the registration system has been changed to make it extremely difficult for non-locals to register. It might be better if you use the 'keep me logged in' setting on the forum when you enter, so you don't have to endure the rather complex captcha we've temporarily inserted. Hopefully, this will die down, shortly.
