I posted this in the 
Facebook group earlier. 
[h=5]So  here's an update - we're still working on the server.  The whole thing  was rootkitted, which means completely reformatting the HD and start  again using a backup of the database and a clean install of vBulletin.  We also have some hosted sites on the server (like the Creature Catalog)  which we're trying to work out what to do with.  Both my sites hacked  within one month; if I didn't know better I'd think it was personal!   Anyway, CM is coming back; it's just proving slightly trickier than we  thought.  Not "we can't do it" tricky, just "it's a bit more work than  we expected" tricky.[/h]
