Bootleg trades are allowed as long as there are no tracks featured on official releases and no money is exchanged - you can swap shows or trade for blanks and postage.
Trades of released items must be at a reasonable market price (check completed items at ebay or
@U2's Collector's Guide) or for comparable physical items. If you ask for songs etc in MP3/SHN/CDr etc format your post will be deleted and account banned. We will not tolerate piracy of in print material on this forum.
Ticket trades for similar seats/GA are fine, as are selling them at face value. You'll probably have better luck at the forum over at
u2tours.com for this type of thing.
