I was GOING to say Kyono but he sux and didn't name me so fux you, Danny. Though seriously, he'd be my bestfriend here even if he's not just a friend.
Of other people that I talk to frequently, Rye, PiP, Squally_Leonharty, Levian, BoB, and Psy would probably the closest to a best friend. Also, I enjoy reading Mr. Milf's posts but have never conversed with him outside of EoFF.
