What you have to remember with forums is that some people join up just to have a nose around,perhaps glean some info or have something to add occasionally but rarely use it full time.

I moderate a car forum with about the same number of members,maybe a bit less and we have a core number of people who continually post, a smaller number who visit now and then and post,an even smaller number who post very infrequently and a large number who are online but only read.

I think this is true of most forums tbh.

If you look at the membership here i reckon maybe 2.5% are regular posters

Not sure how you go about getting the irregular and non posters to post and interract more though.
