I'll try to do this from people that helped me when I first started playing, getting the basics down. These people are Chenault, Adrian, Vaq, Knife.
And now the people who helped me out much much later. Bigmax, Regurge, Soda, Hblair (pretty much all the old assassin guys) and several of the old Jg2 crew namely Urchin, Moot, and JGD44 (I think that was his name at the time) aka AHGOD.
And from there, I passed all my wisdom along to sniper, bighorn, and several other guys I ran into in the DA that I don't think stuck with the game. On an aside note, I'd also like to <S> Nomak not only as a sparring partner, but an overall nice guy who at no charge to me; sent me my old favorite stick (I had one at one time that I loaned to a buddy and never got back) the MSFF2.
