Right, well after a very long, tedious and complicated restore process the forums are back and working much as before! Many many thanks to Digital Ice for his tireless (and ultimately in vain) quest for restoration goodness! Dreamhost had to do it for us in the end due to technical problems.
The shoutbox is missing since it was incompatible with this new version of vbulletin; I hope to have that fixed soon.
The First Class and rank tags are also missing since some templates need to be modified. That will happen later this week.
Apart from that we're in good shape and ready to go. The rest of the website should be ready by Thursday!
