Because of heavy spam attacks I had to close the automated user registration.
New registered user must be validated by an administrator befor their account is usable.
Sometimes this can take some days.
I had to delete some 100'ds of users. There is a achnce, that I deleted someone that was no spammer - if so: Sorry just register again.
Sorry for that, but there is no way arround this in the moment.
