Marty Duren sent me an email today using this service. With all of the concern about “private” emails, I suggest you give it a try. And if you ever decide to exchange emails among 4-6 people to work out arrangements on a public debate, by all means use it! It could just save your reputation. Of course, it can’t do anything for your character, but it might keep its more unsavory dimensions from being exposed, at least for a little while.
