-----Original Message----- > From: Michael.C. Isherwood [mailto:mci3@tutor.open.ac.uk] I often have to phaff around when I arrive at lecture room because the required facilities are not there (usually for me that's white board pens or duster (toilet paper works for the latter) or overhead projector). <<< Beware some toilet paper is too abrasive and can damage the surface of a white board. I find a soft duster useful to keep in my bag. Jill
