Settle the Underscore

About 12 years ago one of my friends had an email address that was something like, The_Man@whatever.com. He must have tried to get TheMan, but it was taken, because he added an underscore to separate the words. This (to me) was a groundbreaking move. And I appreciate that he did it, because every time that he gave out his email address, he had to explain the underscore. "It's like a dash, but you push 'shift'." Life is never easy for pioneers.
