Yeah I posted about this some time ago and used GTAForums as an example.
Now we have over a 1000 members, GTAF have over 66000, so just imagine the many thousands of members they have inactive, that goes for GTABoards, and just about any forum really.
Yeah I've just realised with the amount of members the post count does seem a little low, if everybody posts more it will get better. It might be because we always used to delete spam topics rather than close them, thus decreasing the number of posts.
I wouldn;t describe the problem as severe, at the moment there are 20 guests and 12 members online. Maybe we need a new skin or something to attract more people.
Think of anything just post it in the suggestions forum
