Actually, unlike most forums this one is like joining in on the ground-breaking. Taking part in a forum that is still growing is great because your questions and comments get personal attention and it gives you a chance to build good friendships and solid backing of other like-mined members. In bigger forums it is possible to post and have no one read it or no one respond at all. And try joining into a conversation in bigger sites, it is like being invisible or more often, then not told you know nothing. So if I had to choose a big over-flowing forum or a smaller one that is growing, I would go smaller. One day we may be big, but we who talk now will be friends then in the future.
Of course that is just my opinion.
