If you have a BitTorrent program installed, your download should start (semi)-automatically. You can also try this link to the torrent file for Show 390:
(There's a lot of information on this page. We promise that you'll find at least 2/3 of it useful, so please read on...)
You need a BitTorrent program to download this file. The official BitTorrent client (Windows, OSX, Linux) or BitTornado (Windows, OSX, Linux) will do you well. For more advanced BitTorrent users, uTorrent (Windows) or Azureus (Windows, OSX, Linux) are great choices.
BitTorrent is a little different from other peer-to-peer software.
While you are downloading: The higher your upload speed (i.e. sharing with others) the better your chances of downloading quickly.
After the file is downloaded: You should leave the BitTorrent program open and continue to share the file. Most programs will tell you how much you have uploaded vs. how much you downloaded. Usually there's a ratio displayed; we suggest you continue sharing until at least a ratio of 1.5 (meaning you were generous and uploaded a bit more than you downloaded).
Make sure your firewall is allowing incoming BitTorrent connections! For the official BT client you need ports 6881-6889 to be forwarded. Other BT software may use other port(s). You should make sure incoming connections are being passed by both your software firewall and your router (if you have both). If incoming connections are not making it through, your download and upload speeds will tend to suffer severely.
Although uploading faster means that you'll generally download faster (and get to your target ratio — 1.5 — faster), you should make sure you're not saturating your upload bandwidth. If you're uploading at the full capacity of your connection, then your download speed might actually get squeezed down (it's a TCP/IP thing). So for best results, figure out what the maximum upload capacity of your connection is, pay attention to whether you're using other programs that are sharing your upload bandwidth, and try to leave at least 5 or 10 KB/s of leeway.
Sharing up to and beyond a 1.0 ratio is basic courtesy. But we need people to keep seeding throughout the week for the show mp3s to remain available and fast. If you're using a BT client that handles multiple transfers (like Azureus) and you have a little bandwidth to spare, please keep seeding! Your generosity enables us to keep offering WeFunk in a high-quality format. Thanks!
