How about "The Lost Limbs" Club? No? Well, I've always liked "SF JedHeads", since the Grateful Dead were so big in SF anyway. Since the DeadHeads aren't members (or are they?), I think we could use this unique/SF-only name, with a (possible) tye-dye logo, or even a Rebel symbol combined with the GG Bridge or a peace sign or something. I agree that it does have to be neutral, uniquely SF, and Star Wars-related.
