This isn't meant to be antagonistic and has possibly/probably/undoubtedly been done before, but - is there no possibility of a separate forum?
Now, I have nothing against roadies, it doesn't exactly 'ruin' the forum having roadie threads in here, but at the same time, I (and I suspect others) have no interest in reading about road riding.
So, at the end of the day, it's no massive deal, maybe it doesn't bother others, it's just a thought. Maybe roadies would embrace it too??
