Joe, I don't think a split would starve the music but having said that, I guess it is all academic anyway. Assuming the more likely situation i.e. that there never will be a split here, moderation (in posting) is the only answer.

Amos, go to http://www.jonbanjo.com/forum and view say 10 days worth of threads. You will see that there are posts from several forums listed all mixed together. Follow the create/new topic/ list new forums link. You will see the complete list of forums. If you are feeling really brave you could try registering, logging in and going back to create new topic. You will then see a checkbox along side each forum. Check the forums you don't want to view and click update preferences. Redisplay the main forum list. It will list as before but the posts from forums you have opted to skip will not be on the list. In other words, it is quite easy to allow those who want to view everything to do so but also allow those who wish to be more selective to be so.

Rick, fourms like mine use an extra table in the database to allow the creating and grouping of the forums. I doubt that Mudcat will have any such table so I would guess a multi-forum solution would be far more difficult to achieve here. The biggest problem I see though is where would you put all the "pre split" posts? BS or Music or do you try to divide based on the (inconsistent) use of the BS prefix...?
