Only legal non-album recordings are to be traded. These
include live performances, remixes (singles) and interviews
etc. Recordings of Live's studio work (albums) are not to be
traded. Bad traders will be removed from the list immediately
if these rules are not obeyed.

Traders must have web space to upload their mp3's on to.
I recommend GeoCities, because they don't delete your mp3's
like other web space providers.
