That's due to those who post on it there is no way on boardhost to put for instance subforums in place. We can ensure topics don't vanish but it's very clunky and lots complain each time we tried it.
The other issue is the downtime or slowness we have been experiencing at times, Boardhost half the time don't even bother responding.
We did look at even trying to lift and shift this format before to our own hosted Servers but whilst it looks like this place again it's not quite the same and folks don't like it.
