[Torrent Traveler]

I'm downloading 2 in open btjunkie (there is upload activity too) I am downloading 1 here (about half done) there is no upload activity...
Utorrent is letting the other files upload while downloading, but not on the one I started from tradersden. Will uploading (sharing my download) begin from here only after the file is ready to seed and completed? Or am I having problems? When I first came here (2 days ago) I got a red firewall indicator... (I can thank you) because my Norton Internet Security had become unknowingly corrupted.. Yesterday, they replaced 2009 with 2010.. and now no firewall indicator here... I checked into portforwarding etc. to checkup on things... but still only one way activity (download)... Does anyone know the answer or has suggestions as to what I must do to allow uploads from here? So I can share... do I have to wait until it's finished before I see other users accessing the file? Sorry to be so unfamiliar with things here.
