Hey Eli. I really like your challenge. You should consider building a social network to manage the projects. I know it sounds crazy hard, but its not. Check out WordPress.org to find out how to build a simple site. You can use what's called a plugin to install a social network (There is one called Buddy Press). I just got done building this:

without writing a single line of code (ok, maybe a few lines). Yours doesn't have to anywhere near as complicated as that one. A simple tool to keep track of your groups and projects. Use the contact page on my site to contact me if you have any questions. Good luck brother.
