f you are experiencing Registration problems, here is a few hints.
Make sure you use a valid e-mail adress.
Make sure the e-mail adress is not using anti-spam systems that require confirmation or any action from the sender.
If you are listed in any of the spam databases, well, you are blocked.
Sometimes, the spamblock is wrong, if so, Ill unblock you.
I receicve about 10 bounced confirmation-emails a day, because of the above.
If you are experiencing login-problems.
This is usually caused by errors in the cookies, clean them out, and it usually works.
Other causes could be:
You forgot to click the link on the confirmation-mail.
If it still doesn't work, drop me a mail
