unless you're doing something totally totally wrong on all moral / legal levels ... why can't we just be left alone in this world to do as we please?!? thanks for the feedback, no i couldn't be bothered with potential legal backlash so i think i'll give it a miss. pity as the girls are nice and were up for it, and yes i was guilty of thinking 'more niche-ish therefore more chance of greater £$' but sounds as though it ain't worth trying.
