While we're very excited to see footbag growing and to see people interested in it enough to include it in research projects, we simply can't do any more than we already do in creating this central repository for footbag information.
If you can't get the questions you want answered by actually spending your own time reading every page of this site, perhaps you can convince one of the people in a major club near you to help you.
Just -- please -- don't ask us (especially not Steve).
