We've just found that someone has hacked into the dotproject.net site, forums.dotproject.net, and docs.dotproject.net. We will be working to resolve this issue as quickly as we can.
We will post more details here as we have them.
Update: From what we can tell it's a basic "script kiddy" sort of hacking (read, mostly just annoying). We are working to remove the problem and get things back to normal.
Update: We're back!
