I am not up to date on the newer forum formats (UBB, VBulletin,...) but from my latest experiences, it seems that VBulletin sites are being targeted a lot more by hackers.
Maybe there are more holes with VBulletin, I have seen sites taken down for 3 weeks and losing the content from a full year, even with backups...
As always, you're the chief.... we'll go where you decide to go!
