p.s. If you are using a bittorrent client that supports Super-seeding, try to turn that function on. It guarantees that you send out only the parts of the torrent that aren't currently available from some of the other downloaders. Super-seeding is made especially for this type of situation, where you have a ton of downloaders and only one seeder. This means less uploading on your part. Theoretically you'd only have to upload the last 32% that no one else has.
