New user registrations closed for a while due to a spam attack from China

Well, for now, new user registrations will be temporarily closed, due to a spam attack from China

Dandandin it's a place where the registration is not required to post in the forums, see links or other stuff that is very common to do somewhere else (how many times you saw the irritating "only registered members can see posted links" in an interesting page??), and, if you register, there are no check in the email or other stuff.

Unfortunately, this has been abused in the recent days, so new registrations are closed until I can find an effective captcha to distinguish real people from computers...
