I think a 2300 forum could be useful. I certainly have plans of one day getting a game going. As you might have guessed from Targan's character idea my version of 2300 isn't quite cannon. Among other things I'm borrowing a bit from David Brin's Uplift novels by including altered gorrilas, chimps and dolphins. I have my own ideas about the Kafers too
I think I'll still have a poke through the 2320 stuff to see if any ideas appeal to me...
