Time of wiki wiki

I have recently received a host of requests to present my work incorporating a wiki into my classroom teaching practice (last year). The first of these was presenting to a group of new teachers at Brandeis University. I messed up the timing of the presentation and did not get them time to mess around with my demo wiki. Other than that, it went ok. I set up my presentation before people arrived, figured out the technology in the room, and then managed to turn it all off minutes before I was supposed to present. gaah. No problems, though. Got it all back on and ready in very short order.
