Wing Commander Galactic Conflict has gotten a bit of a face lift. They've got an actual website in addition to their role playing forums now. It provides a little background and cleans things up a little, though not all the links do something yet. They'll also be focusing more on Kilrathi conflict in the near future with their game.
Sylvester has started up a new WC role playing game called Wing Commander: The Second War. It takes some wacky liberties with the WC universe, but if you're looking for outrageous weapons and more Kilrathi, that's where you should go.
