Taylor helped me put together the background PowerPoint presentation for the last SVRR annual meeting. He had never used PowerPoint before, but quickly caught on to it and was an indispensible help.
Taylor, in my past life giving presentations, if it is just information, and you don't want to go into detail, consider 30 seconds or much less per picture. If it is an important feature being presented or discussed, no more than 2 minutes per slide. If it is just background.... well you know, just let it run.
