That's horrible. If it had to be done, I'd like a second thumper forum just like this one. Don't move anything, just lock this one and whatever is here stays here. New threads have to go to Thumpers II, and then Thumpers III down the road. Would be too simple, and I would certainly browse through two identical thumper pages.
There would be 7 times as many threads entitled "what dual sport bike should I buy" and "what oil and tires are best for it" in all the different subforums if it were divided.
