We never actually calculated the preferred mode of communication, but I have a very clear impression that it's email, followed by telephone, followed very distantly by letters. People don't like to write letters anymore. It's mostly email, which is good, because it's good to have a written trace of the advice we give you, and it's good for us to have a trace of what you told us when you sought the advice so we can both remember the same thing a year from now when something happens.
