in Germany instructors have ALWAYS been allowed to be payed, before JAR-FCL and after. And no restrictions to being a club member, either. Club instructors often contribute their pay back to the club, but that's usually optional. Being paid to instruct helped me pay for further training.
Before I got my CPL, it was odd that I could instruct beginners (and get paid for it), yet I was not allowed to fly commercial sight seeing flights!
