It takes me a lot of exposure to recognize two-character acronyms. The only thing that the letters S & G together make me think of is the Trek-like Stargate thing. I didn't realize that HLP was commonly used here at this place for its name at first, and I was never a Galactica fan for the original or the remake, although I did think that the remake was a higher quality production, so I haven't tracked down the first set of BtRL people to their new place after finding the two, GW & here.
Is "SG" the new place that the first offshoot, Galactica in FS2, group started?
