don't bug the mods on this one. When you go to create your .torrent document using your bittorrent client (vuze, uTorrent, etc) make sure to use that "announce" address for any torrent to be seeded to 'Dime.
Once you upload it and Dime accepts it, you'll need to download a new version of the .torrent file, and start seeding using that so that Dime can track your uploads and apply them to your share ratio.
