Ok, so you have accidently deleted a thread. Ok, we all make mistakes, me more than anyone else – apparently.
Anyway, back in the days when I managed to finagle myself into the position of System Manager for a very small multi-user computer system, it was drummed into me that I must do backups, backups, and backups. So much so, that when one ill-informed user found a particular command, and managed to delete something he should not have, I was able to restore from the latest backup.
So have you requested a restoration?
