Forums are the separate themes, help sections, informative places, etc., that you see when you first enter the LEGO Message Boards. You can click on any forum to choose a topic in it, or make your topic and begin posting. You can browse the forums and topics with or without a LEGO ID, but you can only post, give likes and reply to other posts if you have registered one. Each forum is like a category of topics and posts, all pertaining to one main subject. There are 26 main forums. Some forums have a Story and/or Roleplay Subforum.
Each forum contains topics, which have pages. Some forums have subforums, which are smaller forums related to the forum it is in. The forum title determines the subject of the accepted topics in the forum.
There are currently 44 public forums and subforums. Some forums are hidden, such as the LEGO Universe Beta Tester forum.
