My NTN is Krash. My old college nickname NTN location 11172.
And being a smart guesser really is the most important part of the game. knowing which answers to eliminate, and which ones have the biggest possibility is almost imporant as how many right answers you know right off of the bat.
Another thing I like to do is in games where you pick the category, try and make it something most people wouldn't know, like jazz. I figure my obscure knowledge plus my guessing ability trumps all.
