I agree that The Azimuth Project would be better as an all purpose name.
I would avoid creating any more structure than is necessary. As the Kickstarter explains, you can deduct your expenses, and the only tricky part is how to do that if it extends beyond one year. But I think your donors supported a short term fix to a pressing problem. So it would be perfectly fine to dedicate all of your money during this year.
Personally, I think it would be nice if you focused on your talents as a math visionary and educator rather than do too much organizing drudge work. I came here hoping to engage you on the big picture subjects in math. Regardless, you have certainly spent enough time on the Azimuth Project to know whether you want to commit to it even deeper. Still, for me it would be nice to see more activity and interaction and less structure.
