Hello all! I notice most mac people prefer Transmission. I seem to have it on my computer, but... I don't know how to use it. So here are some questions: 1. What IS a torrent really? 2. How do I get to where the torrents are (using Transmission) so I can download them? 3. What do I need to know about Transmission/torrents? I know these are really basic questions -- but I would appreciate some answers. Thank you!
