I was having fun with Emily One, but when the SG all went down the character carried on (How do they do that? I'm not coming up with these ideas I tell you!) and is currently fairly unlikely to get along with a Corperation, especially one into making weapons.
Frankly if people don't use the in game channel, then the forums definitely not going to get used!
Really the biggest thing for this is just getting people and setting a time to do it and (As I forgot to do when I tried) what you envision the SG to be like RP style wise, then turning up!
