Sorry to everyone who tried to register and never got any e-mails. I'm terribly sorry for the inconvenience and hassle this caused. In the meanwhile I'm thinking about a work around in order to get you guys in here as soon as possible.
UPDATE: Forums are updated and I also fixed the e-mail thingy (hopefully). Please let me know in case there are still problems (it should send out registration e-mails almost immediately) and again, sorry for the inconvenience!
