Edits through session2

So, I've been out of the loop for a few weeks (yay :baby:) but I'm trying to get back in the swing of things. I'm going through all the old sessions, getting an [open_camp](https://github.com/jaw6/my_open_camp) install working on my laptop, and trying to remember to update the original documents as I go.

These are things that I stumbled into as I went.
