I downloaded a demo for Homeworld 2, and am now downloading the SW Mod for it, hopefully they will work together and I don't have to go out and buy the full version (cause I'm too cheap for that).
You're right, the expansion won't work with the demo. I had fun fooling around with homeworld 2 though. I think my friend had Homeworld, so its fun to look at the "new" version of it. If its only 10 bucks maybe I'll pick it up sometime, we'll see.
And no one can out stalk me. I was stalking people before you were even born (I started young).
