Well, everyone's a "newbie" at some point. Sometimes newcomers can come off as annoying when they really aren't but it doesn't make you a jerk for being straight with them. If they are a good person, it'll come through eventually.
Besides, I like having guys like you, Janus, and Darth DaNThEMAN. By the way, to answer an earlier question I recall seeing about Jackstain's new name, I believe DaNThEMaN is supposed to be Dan The Man, just without spaces (he capitalized the first and last letter of each word, if you analyze it - but then I might be very wrong).
