About BitTorrent in general, about client's configuration (example) and related areas?
certainly is off-topic at Information Security,
Stack Overflow isn't a good place, as these question are not about programming,
- seems off-topic on Web Applications (because BitTorrent isn't a web application),
- most likely will be closed at Server Fault and Unix & Linux, because isn't about servers.
So? Anywhere? Or off-topic across entire Stack Exchange?
