Make a porn forum.

Everybody loves porn.

I was going to say the exact same thing, huge vouch for this.

Maybe make a forum about making money with Adsense? Maybe have tutorials and tips maybe even plugins and similar things I have thought about doing this and even got a domain but haven't had the time to go any further with it at the moment.

Why create a forum? What will make it different and unique? Will it offer self rewarding/rewarding objectives that users can obtain and stay interested your forum? What motivates you to stay here at hackforums? Are you willing to sacrifice time and money for your community? Ask yourself these questions.

see here's the issue with starting a forum, theirs thousands of forums for any idea you can probably toss out their
less you find a way to make it unique and to draw users from their current forums etc. i don't see the point
