This is tough. It's basically "who's on your friends list" list. but I suppose I'll give it a try.
Well, I wouldn't miss Jeff (ND4SPD) because I can always phone him or talk to him on MSN or make him my ***** again

. I'd probably miss Swift if he left. We don't usually get along, but I admire his courage. Then there's McLaren'sAngel...
GTP wouldn't be the same without her. She's kind of like the Phoebe Boufet of GTP.
Then we have eMad/Emad, who's a pretty good guy that I've gotten to know quite well. I'd miss him.
And then Rick. Rick, Rick, Rick. He was probably one of the first members whom I really remembered, as I started hanging out in the Convo Forums he and I were usually the ones in there.
And then DQuan...oooooh, drunken Duncan. Can't forget him. Gotta have the English sense of humour and lifestyle around here. He's a good guy.
Famine. He's a guy I'd miss. I'm not sure if it would be because of his somewhat sarcastic sense of humour, or simply because of the wealth of information he's brought to this website.
And I can't forget Emohawk, who's got some of the most direct, and some of the most sensible posts, plus I've gotten to know him a bit, too.
Now DA. I don't think it's any surprise that I'd miss him, he's an interesting guy, and it's good to have him back.
And the Aussies. Oooh boy, those Aussies. I think I'd miss all of them. You can't get around or away from their sense of humour and alternate culture brought to this community. And Radicool's Mum, of course.
But, I can't forget a6m5. I've found some of his posts to be quite enjoyable/funny, and I agree with him on a lot of things.
And all the newbs. *sigh*. You can't have a village without an idiot.
And Blackbird/Eric. Ohh man. Hehehe. The times I had with him. You were good punching bag Eric, don't take it too seriously.
Then, TwinTurboJay. This guy usually makes my day, he's so cool.
Andendere's Doug. Dougy boy...oh man. He's kind of like a mixture of Snake and Professor Frink, me tinks. Can't have GTP without a Doug.
And last, but certainly not least, Brian. Great guy, and owes me premium.
I know there's more, but I can't think of them. I know there's lots of people who I'd definately notice if they went missing, like sn00pie, Sage, ExigeExel, Zach, ultrabeat, small_fryz, danoff, Ev0, skip0110 and James2097.
