It was pointed out that I'd neglected to have a "presentations" page, so there was no easy way to grab stuff from any of the presentations that I've had the chance to be involved with.
I just added a new "Presentations" section, listing (I think) every presentation I've done since I started here at the Learning Commons. There may be a couple that I've missed, but at least the "big" ones are there. I'll keep it up to date as new ones come online.
I was going to create a "Presentations" page directly in Wordpress so it would be easy to maintain, but it appears to not like sharing with the /presentations directory of the website. So, for now, it's a hand-rolled static .html file until I figure out a better way to make WordPress and Apache share stuff on the same path...
