I decided to log in for this one.
OP asked a question. You obviously do not know the answer because you just made a stupid, insulting reply. Perhaps if you don't know the answer, don't reply. I don't know the answer either, but would be interested in knowing the answer as well and would have asked the question had the AC not already asked. But instead of an answer you just shit all over it and are apparently offended that it got asked. Get over yourself and realize that some people aren't afraid to ask questions when they are ignorant... you might want to try it.
