First off, thanks a ton for working on this project OP and everyone! I think it's a great effort and I'm excited to become more involved. 10 is definitely over what I can pull together while starting up/running a business very full time. I like the concept of having to contribute to gain access but I think 5 or less is much more reasonable. In the end, this limitation isn't meant to keep all but the hardcore away, it's just meant to keep the free-loaders out. Just my two cents:)
Keep up the good work!
