All links should be underlined so that they stand out as links. I have perfect color vision and it's still hard for me to recognize links on our page since they aren't underlined. I can't imagine how difficult it might be if you're colorblind.

It underlines automatically on the backend so I don't really understand why it doesn't on the font end. When I've spoken to other companies, they're all surprised this isn't already happening. It seems like a simple fix that would make our lives easier and our websites more accessible.
