Thanks! Actually, it had not occurred to me to use ppt, but given the option I think it might be a good idea for the reasons you mention. Also, I tend to treat these things more like a short lecture than a "paper" per se - I can't bear listening to someone just read a paper and try not to do that myself - so since I use ppt in my own lectures it makes sense to use it this time, too. Good for organizing, as you say, and to highlight technical terms or quotes.

Handouts. Hadn't thought about that, either.

I guess there's likely to be somewhere I can print things on site??

I'm glad I'm not on the first day. I've got time to suss things out and see what other people are doing.
