I am not really qualified to talk as I have only done a couple of static line jumps (time, money, weather and work, bah keep on conspiring against my AFF plans) so dont consider myself a skydiver (yet) but having spent years climbing, almost to the exclusion of everything but beer, I still consider myself a climber even though I havent climbed in a couple of years (damn these grown up commitments). I guess if you've done it and intend to do it again, yes you are, if the intent isnt there then its just been an experience.
Experience is a series of non-fatal errors.
