Recently whenever I'm modded up (interesting, funny, insight) someone invariably mods me "overrated". I'm begining to think theres a perosn out with mod points continously out to get me. My last comment was designed to be informative and it was, the only slip up was in labelling the three stated logic as "tri state" but then several of my textbooks also call it tri state so I don't see the big deal. If my posts are flamebait etc.. I don't care if there modded down. Yet how is a post which answers a question and then goes on to explain the difference "overrated". I don't see how a person could disagree with the material in question.
