Capt. Chris--

Look at the numbers of folks who are logged in.

If they are actively searching, reading, etc., that says something other than the number of posts being uploaded.

Think about the legacy content and its value in terms of knowledge not readily available elsewhere.

The number of active posts alone does not account for the value of the Forum. I go back and look for stuff that clarifies something for me, but don't post new topics when doing that.

Also, maybe members are using the messaging feature to talk to one another?
