I would recommend getting involved with Udacity as a classroom mentor/forum mentor/project reviewer. All you have to do is demonstrate enough domain experience for whichever course you want to help out in. You can do that by either completeing the course in stellar fashion or demonstrating your skills via a stellar personal project. For more info on it, you can check out my other comment from a couple of days ago:
