Use Forums Effectively - 1
First find a forum you like. It's not difficult. Nowadays you can find a forum on just about any topic you can think of. If you have a hobby or sport, why not share your passion?
A good forum should be well moderated and have enough active members.
Forums where you have to register to participate are better than free for alls, where you may get trouble from spammers etc.
