adding some feedback instead of broken page

Hey Duane,

Doing a little Git practice today, and admiring your Great Dane site.  I noticed a couple of the buttons linked to missing pages(about & resources), so i switched the <a> out for a bootstrap javascript button with a little popover.  I did notice there is a resources page in your repo, it must not be on your webserver?  

Anyway, feel free to use, alter, or not use these changes, I was really doing it just for some practice using git.

See you later!
