Well, the idea with the tickets is that it's designed so that near the end of the swap, you have so much that it's basically an unlimited amount. This ensures that you get every single item you care to receive. You could potentially end the swap with hundreds of tickets. At the end of the swap, they all disappear.
Right now everyone has a lot of tickets so there's no need to donate them anywhere.
I'd rather not make them transferable for many reasons...
