I've experienced two odd conference room configurations in the last month, and I thought I would share them with you.

When I'm booked for a training, I send the organizer a diagram with my preferred room setup. I request classroom-style seating, the screen to my left (in the corner, so I can be in the center), a small table to my right for props, materials, water, notes, etc., and a flip chart either between me and the screen, or behind me.
