Well, as for the best poster of all time, I'm going to have to go with PROfessor. That guy almost had me in tears a few times, with his "who here has a computer" thread, and his hilarious sigs.
Most intelligent: Seeing as there's only about 10-15 people in this entire forum that are capable of carrying on an intelligent discussion, I'm just going to name a few of them. 2000warrior, TarkanX, MVC2, VIRUS, viper2040, SSJKarma.
