I have been an instructor at Hilltop skate camp in Princeton (http://www.leaguelineup.com/miscinfo.asp?menuid=30&url=princetonrecreation&sid=188655905) for two years running and have taught everything from the basics of riding on flat ground or down ramps to more advanced flatground tricks like impossibles or varial heelflips as well as lip tricks like 360 rocks or frontside grinds and ledge or rail tricks like 5-0s and crooked grinds.
