My advice take it or leave it as you see fit. Getting people to use your forum is bloody difficult. SimplyMaya had between 50 and 100 new people a day sign up for the forum, you see them post? Unless you have a USP getting your forum going is next to imposable. Especially with a forum like yours as you have categories for everything. Which means your forum is always going to look empty especially at the start, and empty forums are like empty restaurants no one want to go in.
Cut it down to 3 or 4 forums and target a more specific group of people. Then give them a reason to join and you may just stand a chance.
Just my 2c. Good luck
