Personally, I've found my T's physical presence is really important, because if you email, you miss all sorts of non-verbal and unconscious signals. Bear in mind just 7% of our communication is verbal. The rest is in tone of voice, gestures, facial expressions and other things we're not even aware of. That, and you won't get the experience of having someone listen to you and hear you.

I'm not saying you shouldn't try it. Just things to think about.
