if you're on a mac, i recommend using "transmission" as a bittorrent client. link is in their faq. nice thing about the app is that you can set individual ratios and track your overall DL/UL ratio, and this is very important for DIME, b/c you lose the right to download if you don't keep a .25 upload rate, or if a torrent is 1GB, you're expected to allow at least 250MB uploaded from your computer.
