Oh yeah, thanks but it's not really the program that's the problem. Really even for free torrents I have this issue.
Since emule has been unreliable and with the proliferation of file sharing sites, it's been hard to figure out when a file is really going to be rare. You see it and think it's going to slowly increase in seeds and then suddenly you have a rare warez/book file w/ only a couple of seeds even if you took a month seeding it. Really makes it hard to be a decent sharer since unless it gets abandoned or it's a private site - there's lots of hoops with re-seeding and requests.
With usenet not really a seeding service, things get even more hectic. Do you or don't you? Especially w/ limited internet speed and HD space.
