Ian's suggestion sounds good to me. (So does his CD.) I'm starting to lose track.

The other idea that's occurred to me is sending CDs to people who ask for them, and asking them to make a donation to the Mudcat. I've done that a couple of times -but that was before the CD swap idea came up. Maybe there's a way off combining things - every time you get back a CD you like, stick a donation in the post or the bank for Mudcat?
