If you need urgent help, contact VSTF. There is nothing users here on Community Central can do to help you unless they happen to be VSTF; in which case it would be more expedient to contact them via the other wiki. In general, the users here on Community Central are just regular users. We do not have any special permissions or tools to deal with vandals. In fact, local admins/mods are better suited for this stuff than we are. So if they can't cut it, there is no way we are going to.
