Jim Pansey, I'm definitely in. I would LOVE to see Sorel again!
On the practical side, however, why don't you simply have Sorel post when she wants to come to Ottawa and begin taking bookings. Worse case scenario, if there is not enough interest, she cancels her trip. It is a lot easier to commit when you know the dates and times in advance. That's exactly what the other Toronto SPs are doing and they don't seem to have any difficulty filling up their calendar. With Sorel's reputation, she'll take Ottawa by storm.
