I'm off to bed, but feel free to post if you are interested. Room for 10 USA members.
By the way the small bubble mailers I use for these only cost $1.22 in postage to send to the next person; (EDIT: Sometimes it's $1.39 if 2 oz.; just look at whatever postage is already on the package when you receive it.) You don't even need to take a trip to the P.O.-- just stick on the stamps, drop the packet in a mailbox, and you're good to go.
