I tried to use it about 4 years ago and submit helpful answers etc. Apparently I did something wrong and I couldn't submit anything. It was a very hostile introduction. Over the last 4 years there have been numerous times I would have contributed a valuable answer but since I don't have a working account I cannot. No, I'm not interested in wasting my time trying to get my account working. I don't care about SO "reputation".
