I changed my mind about the backup.
My last one was a bit too old (I'd been lazy) so sent out a mass email saying we needed to work together to get back to how we were.
Anyway, in less than 12 hours we've had 120 new threads and almost 900 new posts - and the atmosphere had been better than it has for a long time - I'm almost grateful it went wrong.
(Good job it wasn't the memberlist that broke though)
