I allready have downloaded some files via "regular" http. Then I saw that the provider (e.g. liflg.org) also provides a BitTorrent download. Now I want to seed the files I allready downloaded.
Is that possible with KTorrent? If yes, how?
I don't want to create an own torrent or even track it myself. I just want to add me to the allready existing torrent...

It's not yet possible but we are working on that. It will be possible in the next version hopefully.
