There's a shit ton.
Aydee. MikeM. Jay (Construct), Ian Williams, Polly la Grea la Anna la laPly, Boomka, Jonescrusher, DuncanFendyoke, Matt Smith, DMC, the big H, MAD, Dray, Kona...............and I'll guarantee there's another 20 odd that I'm missing, that should come immediately to mind if I really put some thought into it.
All of 'em have been excellent conversationalists and provided me with food for thought over my 9 odd years here. I miss each and every one of them in some way shape or form. And this place isn't quite the same without their input.
