When making a forum, the hard part is making the actual forums. But there are always the ones you use in every forum you have owned, which make the job easier. What I'm saying here is: everybody always re-uses some sections. What are these sections for you? When I make a forum, I always include the stuff you see on every forum: News, Suggestions, Questions, Introductions, and most of the time and Off-Topic section. Most of these are self explanatory for reasons, they are a need.
