Hi Michael,
We are looking to do both. However, if you want to know a focus, our focus is to look for relevant bannerads which would complement our site, rather than having to use banner ad networks. As you know most of our members take advantage of our free service so we have to fund the site in other ways.
An effective method in promoting the site to gain new users and build community is whether or not our members can reach out to basketball forums to arrange banner exchanges or some sort of marketing deal. Let me know if I can help support any of you to help BB grow in Austria. Thanks.
Andy
