Here are the files, attached. I'm thinking about the best place to make them publicly available, whether a Dropbox link, in my Dropbox public folder, at a gmail location, or other. I guess everything is susceptible to link rot 😞

Wow! That's what happens when an IT department at a university changes servers and doesn't inform the users. I'm sure I have the files around somewhere at school. It's easier for me to check from my office and I'm at home right now. Stay tuned ...
