Has Joe not told you? I booked both masters in advance, for this very purpose. I knew you and Jennifer would need a master, and so you have no choice but to sub-rent from me. Don't worry, though, my price is cheap. In fact, free! All you have to do is allow me to set-up one thin, unnoticeable antenna; one modest, unthreatening microphone; and one small, unobtrusive chair. Then you must allow me to sit on that chair and broadcast play-by-play commentary during your networking sessions.
I promise to use my "indoor" voice.
