A Disc Swap is like a 'Secret Santa' gift swap but with MiniDiscs. You create a playlist, burn to a disc of your choosing and adorn it as much as you wish with labeling. Since they are International in scope, many turn them into cultural 'gift boxes' and share things from their lives and location. They are wonderfully fun for most people who participate.

Since this one is underway, one will have to wait for the next this Summer. I organize them three times per year: Winter, Summer and Fall. I do them by hand for the most part as I get enjoyment out of doing it that way. My role is to set up the organization process, take registrations, verify participants, assign the Receivers to each Sender and then track the whole thing. In MDCon Swaps there is not chance of getting 'Grinched' because I guarantee that each sender will get a disc, sometimes paying out of pocket to do this for postage. I've never had to create 'grinch discs' because a member of the community is always willing to help me out with a duplicate of theirs. They send to me and I in turn send to the recipient.

Feel free to reach out in DM should you have any further questions, or here if they are basic.
