Just to poke my nose in here; I used to do the following, all peripherally related: 1) administer an email system; 2) Sysop of a company Bulletin Board System (no longer online); 3) Sysop of a Compuserve forum; 4) Moderator of a Yahoo Groups group (still active, 4000+ subscribers.) With all of those experiences behind me, I think that QR and UUU are spot on. If you want to increase your traffic, you limit your forum fragmentation. The highest traffic forum is of course a single forum, but that gets WAY noisy. The more fora you have deployed, the harder it is to find something (unless your underlying system has a GREAT search tool) and the less perceived activity there is (because every forum only has a few messages in it.) All of this, of course, is driven also by what you want your message board to accomplish, and how long the board has been in operation and with how many subscribers. A highly technical forum, with a high number of subscribers (like the Zed) is much more suited to forum splits than a general discussion forum, but they need to be managed carefully. Cross topics like QRP are difficult because they are neither fish or fowl. The one fatal mistake that new operators make is to set up their board with a million fora, each of with a welcome message (and maybe one or two more.) Start with fewer fora and split off only when it becomes difficult to find stuff.
