I have a day job, so the freelancing is part-time. 10-20 hours/week maximum. Unless it's something really inspired, for which I want to make an exception.
I prefer to go old-school with communications -- handwritten letters, ideally with quill/ink on parchment, delivered by horseman, or as required, horsemen (armed). Seriously though, I like e-mail. Good at typing with 10 fingers on a full-sized keyboard, not so much on a phone. And don't really like talking on the phone either, I'm sorry. Will do it of course, if the client insists, but usually not the best use of anyone's time.
