I say keep it in GD etc, just for the fact that more will notice and welcome... nicer atmosphere?
I dunno, just seems to deviate away from what did happen, someone reads GD mainly they pop in and say hello there. SC say hello there, hardware/cases etc. Sometimes in repsonse to a thread, they just sign up and post from there..
No harm either way, you just might end up with the same people always going to look to say hello to the new people?
