All the usual stuff about decent quality discs. I'm restricting new trades to DVDR data discs due to too many poor audio burns audio received. Everything is available in FLAC/shn. Feel free to write on the disk in felt pen if it helps keep track...I do for my own benefit. Remember, it's only a hobby so don't get pissy if work gets in the way of promptness. I live in a small village and can usually only get to the sub Post Office on Saturday mornings.
