well it works like this we have to install it on a server
after that we need to upload the torrent to the server and it will keep downloading..after download is done we can download the file from that server directly...
One of free seed box is http://tor.imageshack.us/tor/
if u have a web-server try Torrentflux
well i use a bit long method coz i 1st download the file to image shack torrent service and import the file through rapidleech to my web server from there i download the file directly but the case is my webhost supports max 1.4Gb per file.. so mostly i download files 700mb so it want be a problem..
