Hmm, I might try actually answering the topic question while I'm here, eh?
Of those individuals whom I've already met in person, the ones I'd be excited about meeting again would be Chupperson, Lizard Dude, Luigison, MEGAߥTE, Andrew, David, Fifth, and even Frog. It was fun getting to believe for six days' worth of waking hours that we lived in close enough proximity to enjoy each others' friendship without the Internet.
As for those whom I haven't yet met, I'm most interested in meeting Deezer and Sapphira because they were supposed to have been present when I met the people above.
Looking to the rest of the people here—who are by no means less important—those who strike me as folks I'd most like to see face-to-face are GoombaDoom, Black Mage, Eclipsed Moon, Insane Steve, King Boo, Markio, Nameneko, Suffix, TEM, Vidgmchtr, Yoshisaurus Rex, and even JJ. For the most part these are just the names of those whom I know best here. While there are probably many others (Bird Person, Dairy King, Koopaslaya, Screech, etc. etc. etc.???) I'd also enjoy meeting, I kept the list to those whom I feel I've gotten to know a little better.
Wait, was I supposed to give only the top five or something? If so, whoops. If not, whatever. I don't feel like going back and (re)reading earlier posts after typing all of this.
