It's all very well doing a poll now, but you'll never really know unless you trial a split forum for a month or two (long enough to people to get used to it) and then ask people what they prefer.
Keep it whole, it's like my internet boozer, all topics are welcome.
I even enjoy the away supporters, if anyone becomes too much of a pain just ban them
just a thought if the big board was kept for football/ Albion related stuff and everything else (arse wiping threads ect )in the other stuff i wouldn't really be necessary to split it up
