As it currently stands, when I download torrents using LimeWire the uploading stops once the download has completed. Is there a way to keep a torrent uploading even after it has stopped downloading? I realize it is open for uploads on the Gnutella network but I can't keep it seeding for other torrent users. If there is no way of doing this, this should be considered as an option to implement. This removes the whole idea behind BitTorrent and you will be banned from many Trackers if you do not maintain a good down/up ratio.

you will be banned from many trackers just for using Limewire. If on private trackers, use either Azureus 2.5.0.4 or uTorrent 1.6.1
