We are going to migrate to a faster server soon. No need to worry, nothing will get lost. I'm glad the forum is still alive and I will continue to support it.
So previous moderators decided to set registration to manually approved, which is unfortunate. I've removed this limitation. Registration is automatic and do not need approval anymore.
I've fixed an issue in the mail server that was preventing new signups to join the forum. Hopefully we will see new people around here very soon. More than 2800 signups that got stuck :(
I also enabled Google Sign In and will update the forum software soon.
