Well, personally, I like the idea of keeping both forums active. CFS3 did that for ages with Netwings, Groundcrew, Italian Wings, SOH etc. Not all these were forums of course, but they were all homes from home. Having two active forums well supported is a much healthier situation for whenever something nasty does happen. If you can't get your downloads one place, there's always somewhere else to try.
I like the CA forum, and don't recall having any issue whatsoever with admin, and the moderators were always discreet and even handed, and completely on the ball. OK the first real problem has been a big one, and seems to have caught the CA team out, but we have real friends there. I don't question the decision to relocate the HQ to SimHQ, but I just hope it isn't the end of an OFF-CA era. I think we'd both be losing something good.
