You can try a Direct Connect: http://www.gnutellaforums.com/showth...threadid=30911 or if they have a little smiley beside their file in the downlds window then you can send them a Chat message. For chat see: http://www.gnutellaforums.com/showth...threadid=31572 & also http://www.gnutellaforums.com/showth...threadid=33584

But they'll need to be online of course to receive the chat message. But they might also just be away from their computer.
