There seems to be a lot of frustration over people who are registered and don't contribute a lot (like me!).
To be honest, I started by collecting 16mm. Last year, I bought my first 8mm projector - the first time I tried to use it the speed knob broke off, so I joined this and the other 8mm forum in search of advice on how to fix it. After I fixed it, I put the 8mm projector away and went right back to 16mm. Forgot about this and the other 8mm forum. It wasn't until a few months ago, when I started collecting super 8, that I started looking at the two 8mm forums again.
My point being that, just because there are 120 members, doesn't mean that there are 120 people who are sitting in a dark room each night reading without contributing. Some may have joined out of curiosity, or to get a quick answer to a question, etc. etc., moved on and never bothered to come back to de-activate their account.
I remember when I joined my first forum, when I first got into 16mm - I spent several months just reading through old posts, learning and learning and learning. It was a long time before I ever posted, because, quite frankly, I had nothing to say.
Some people like to post multiple times a day. Some people, for whatever reason, never post - does it really matter?
Anyway, to get back on topic, I agree with most of the posts I have read on this subject that topics without film is fine, and can be interesting, as long as the primary focus of the forum is film.
