yeah its like limewire only way better... you first need the program...I like vuze...then you need a website to find your files...i like isohunt.com...go to the website and search for waht you want and download the "torrent" file...once you have that, you open the "torrent" file with your program (ie:vuze)
once you install vuze...it will set itself to automatically open the torrents you download and save you that step...
now that vuze has opened the torrent file, it will begin downloading from multiple peers (much like limewire)
http://www.vuze.com/appwww.isohunt.comanother way to find torrents is to just google your search terms with the word torrent at the end
hope this helps and dosent confuse
