All answers will be sent by return e-mail.

The only internet answer site where answers are always live, never pre-recorded. Well, if he answers, and doesn't just paste in some old stuff. And it took him an hour and forty seven minutes to answer me last time, so "live" is kind of a marketing phrase, not a response time expectation. Oh, and if you don't have a local e-mail client set up properly, then you'll never get an answer at all. Still, you get what you pay for, and more, in my humble opinion.
