As long as you are reasonalbe your rules are fine.
CDR only (I don't have tape, DAT or minidisc facilities)
DAO only (unless otherwise specified)
No MP3's (unless otherwise specified)
Prefer to trade between 6 and 14 CD at a time (more economical for postage)
First to contact, first to send (unless we have traded before) - but very flexible
Setlists and dates would be nice, artwork if available
A reasonable quality rating would be appreciated.
