If you really do mean that you want a completely seperate forum for WoT then just take a look at the MC forum. It does work but the forum part is never really active . If you still want a completely seperate forum then get an enjin forum- it has a univeral accounts, meaning people from SG WoT could easily join SG MC and vice versa if they wanted to.
Though I still think that you just want a sub-forum on this site. The above is just in case i am wrong.
