I'm another former BitTorrent user. I just learned of Azureus in the last few weeks (while trying to figure out how to 'super seed' -- which Azureus supports), and I'm sold. There's a bit of a learning curve, but that's a small price to pay for the huge increase in additional flexibility. The online documentation is pretty clear, and there are online discussion boards that are helpful, too. Even at this early state, it's a very good program... and with the obvious hard work and regular updates provided by the programmers, it looks like it will soon be a great program!
