u have to understand the idea behind a torrent is totally different than the conventional p2p we know
a torrent is a small file containin information abt a tracker url ... which will redirect to the "seeder" ( more on this later )
a seeder at first is a person who ur downloading from ... a person who has the whole file and is letting ppl to download from him
a leecher .. is one who downloads and doesnt leave the torrent open for anyone else to download
(btw ... u have to click on the torrent ... and then ur torrent software will start the download ... if u have the individual window kind of torrent like bittornado .. then multiple windows will be open .. and ull have to keep these windows open to seed .. if u have something like azureus ... then once the torrent is done .. it moves to the lower frame which is for seeding .... as long as the torrent is there ur seeding ... once u stop .. and remove from list ... ur no longer a seeder )
a reseeder is one who starts seeding an old torrent on whim/request
i think mostly that "cam" extension needs to be renamed
that term "CAM" in the filename only signifies the kind of print ..
look at the link i gave u
everything is very clear and i dun think anyone else is gonna take the pains to decode and explain it
hope it helps
