Go to the VacationHold page:
**If your account will be on Vacation Hold for longer than 21 days, DO NOT leave your Wishes on Auto-request, unless you have arranged to be notified when your CDs arrive.** If you leave your Wishes on Auto-request, they will be fulfilled when you are first in line and another member posts them. If you don't mark the CD as 'Received' within 21 days, the CD will be declared 'Lost in the Mail'. Then, the next available copy will be automatically ordered for you. To prevent this from happening and ending up with two copies, you should place your Wishes on 48 Hour Offer. You will not lose your place in the Wish List line, but you will not receive an offer for your CDs until you return from Vacation Hold. If you will return within 21 days,leaving your Wishes on Auto-request is not a problem, because you can mark the CD as 'Recieved' before the system declares the CD as 'Lost in the Mail'.
