i agree with instructing doesn't hurt to get some experience and get bit of money along the side lines. Thing that worries me is the logging the hrs you can only log hrs if the person you instructing is doing their ppl because they technically dont have a license so they not qualified yet right?, but once they have their license you the instructor cant log anymore hrs especially if you instructing them for the night rating or instrument etc I'm guessing FAA you can log but JAA/JAR you cant.
