When I click "sign up" it always clears the password fields and says that I have to fill in a password.
Can you try with a different browser? I just tried it here with Windows Chrome and it all seems fine...
Thank you it seems like it doesnt work with Firefox.
But in Chrome I get the massage "Your account was not verified yet" now. I have clicked on the activation link from the e-mail multiple times
...ok after a long waiting time it works now .
But you should fix the Firefoy problem. I think a lot of people are using Firefox.
