A forum is an online notice board where users can post questions, post answers or comments to those questions. In the Official Ogame Forum there are also sections for Role Playing, Fan Art, and a Hall of Fame. One of the newer sections is GNN (Galactic News Network) where GNN reports post interviews.
Many alliances also have their own forums where members can exchange information. If an alliance has a forum it can normally be accessed via the Homepage link on their alliance page.
