Hey web devs, I highly suggest that you bookmark this tool for when you need to do accessibility testing. http://wave.webaim.org/
I thought I had gotten everything and it found 8 issues that were fairly high priority. It gave me dynamic bookmarks so that I could automatically navigate to the problem, explained why they were important for accessibility, and told me how to fix it.
The ADA has started suing websites for lack of accessibility, so take this seriously!
