If you like using torrents, i suggest you use bitlord as bitorrent has been blocked by alot of torrent websites, utorrent is good aswell, but if you
dont already understand.
trackers are the places you download what ever you want from, the more trackers is usually better and if it has no trackers it means it wont download
at that time.
The only bad things about torrents is you need a torrent manager to download, its similar to limewire, kazaa type applications but you find the
product on websites not throught the actuall application, i hope this has helped
