Im not trying to be a smart ass but this question is really asked too much. Seems like every week we see X or H pipe, or we get the 3.73 or 4.10 question. But I guess people have no choice you cant run a search on x pipe you get the "The search term you specified (x) is under the minimum word length (3)" message. Wish the search function was more usefull so people wouldnt ask the same questions all the time.
