First off, you need to have the SS option turned on before you start to seed. If you don't, then it won't go into SS mode.

Second, as Rider said Azureus is smart enough to know when *not* to use it. So, if you have it set and are seeding a show and suddenly you aren't the only seed, it's going to take you out of SS mode automatically.

And, you can see if you are in SS mode in the My Torrent tab if you have the Status column there. Instead of saying Seeding, it will say Super-Seeding.
