I prefer to do shn or flac filesets onto DVD's thru the mail.? This way we can exchange more music on less media.? No cheap cd's or dvd's and no more than 5 dvd's at a time or 10 shows onto cdr's at a time.? One to two weeks upon receiving media in the mail for return.? Pretty laid back about times to get returned shows but?please no more than 3 weeks.? This should be plenty of time for even the busy people.? ?
