I thought it's possible to go from version 3.8 to 3.7 and get all the forums and user?
I've tried to look at it but only get all the user with no forums have been created is there someon that can tell how I get the forums?
Hope you have a backup ... 3.7 and 3.8 are very different beasts sure to cause you a lot of pain to try to revert. Better you should find out why you are not liking 3.8 and fix it.
