I doubt that a board can make any money from any of the banner companies. But if you run your own system and have targeted banners then that is a different thing altogether.
That is what we do -- we run the banner server, do all of the selling of the banners, design most of the banners even. We also sell some T-Shirts and things, but they don't generate enough money to really cover much. It is the banners that are paying the bills for us.
But like I said, our banners are specific to the members and something that they are actually interested in. And then we offer some extra features to allow the members find the advertisers and also give the advertisers some incentive to keep their information and offers current.
But it is a lot of work also! But it is paying the bills, not capable of providing a living or anything, but it is paying for the servers and bandwidth currently.
