In the future I would recommend switching to XenForo if it is at all possible. It is one of the better up and coming solutions that just might surpass vBullitin in the future (if it hasn’t already [at least in some areas] ) and is extremely user friendly.
In what reasoning would they put so much effort into a conversion, security recheck, and other hassles that come with a new forum setup when the current one works just fine?
It is just a possible suggestion for the future. Nothing to get worked up about.
I think there too much effort in to extending current system to think of switching in near future.
