I can't reply to any messages I always get this error message:
you do not have permission to access this page. This could be due to one of several reasons:

1. Your user account may not have sufficient privileges to access this page. Are you trying to edit someone else's post, access administrative features or some other privileged system?
2. If you are trying to post, the administrator may have disabled your account, or it may be awaiting activation.
3. To fully activate your account, you should click on the activation link on the email that was sent to you when you registered. If you didn't receive any activation email, you can have it resent.

I think I have activated account, but anyway i pressed resent link and requested activation code to be resent, nothing never came to my email.

Hey guys, really what do I need to do to be able to reply?

Please check any and all spam/junk email folders you may have. The message commonly becomes stuck there.

I had the same problem - the system here refused to accept any email address at my domain. I requested resends of the confirmation email, but nothing ever arrived. The address worked fine for the bugzilla installation here though. In the end I had to change it to use the email address from my ISP instead.

Ok. I got this working now.

Firstly: I can't remember for sure, but I think I got verification mail to my email when I first created my account and followed the link so that my account was activated.

Still I couldn't reply any messages. I changed my email from own domain to gmail account and got new activation mail, after that account did indeed get properly activated and now I can reply.

The weird thing is that I never got reactivation email to my first email account. Well thanks for pointing out that some emails simply does not work.
