Hi Guys, I just stumbled on to this site: http://www.corewerkz.com/2008/03/15/torrents-a-complete-mac-tutorial-featuring-transmission/ It shows detailed instructions on how to open the "port" of the Transmission program. My port is closed. I'd like to ask, is it worth it adjusting all the settings to get the port opened? How big is the difference in speed? Anyone tried this already? Thanks!
