I'm part of a forum and we are interested in selling ads to make the forum more profitable. I have no idea how to do this or what to charge. I'd love it if some of you experts here would take a look at the forum and let me know what you think about it in general and how much you think I might be able to get for advertising. If you are interested in giving some helpful advice please PM me and I will reply with the forum URL. Thanks in advance.
