I came in late on this but it is something that I have been doing on another list for three years now. We have settled on two "rounds" a year. I just mailed my Round 7 double disk set out today.

We send all of the disks to a central Hub who collates them and mails them back out as a set to each participant. We of course include the return postage and mailing lable. We take turns volunteering as The Hub.

This round has 26 participants which means I sent 52 disks with cover art and all the trimmin's. It's a lot of fun.
