Unfortunate that you will not separate the forum section. It's not hard to do, I'm an admin on a couple other forums and know what's involved, just have to be bothered to do it is all
the way I see it we don't need 'more traffic' in the 1m forum by way of lost 135i owners. 1m owners will find it more easily if it's got its own section like the m3 etc. It's a pretty obvious forum structure oversight and shoild have always been separate imo.
