www.stardock.com/products/sf/fleets.html just updated, please let me know if you wish to add any information or if any information needs to be changed. I am currently listing only 'active' members of each fleet who have been seen on SF recently, I'm not listing long-inactives who have abandoned SF, because doing so would be... rather pointless.
Current listed fleets are (alphabetical order);
Alpha Clan Elite
Knights Of Arcea
Tribal Warriors Brotherhood
Again, please check the Fleet Register (see link above) for information on these fleets.
