Remember this: The trading of paysite clips is not only not permitted under TickleTheater rules, but is also illegal. The trading of material from forbidden producers (FM Concepts, Realtickling, ect, the full list is in the rules of the clips section) is also not permitted. Trade only free clips distributed and permitted for redistribution by the producer(s).
As Missy Val said, "Many producers already share large amounts of high-quality free material with this community -- let's show them our appreciation by buying from them once in a while instead of talking about trading."
