Mudcat is a great forum even with its faults.

However I wonder if you've thought of using PHP technology - they have a ready made forum template that you only have to customise and populate.

It also make membership easier to administrate w.r.t. trolls.

It allows photos and files to be uploaded (if you wish).

And threads can be separated out making them easier to locate, read and respond to.

Some I visit regularly are (and I list these not because of the contents but so that you can see how they work):
