I am one of the Administrator's of the Clone CD forum.
It would appear that there is some issue at the moment. I cannot get in contact with the site owner at this moment, so therefore the issue cannot be resolved yet.
All I can say, is that regardless of what happens to Clone CD, the forums will remain open. Even if I have to host them myself.
There is a forum here, so please use that.
[EDIT]Ok, we know what the issue is. It will be back up soon[/EDIT]
