Have you upgraded your forum to the latest version of VB?? If yes, how is it working? Would you like to share your experience please?
If your forum does not have hacks, there is no reason to wait. Upgrade will take less than an hour of your time. If you have custom hacks, its not a good time for upgrading to 3.7.x as 3.8.x is about to be released. (Yet apply security patches while waiting)
