A simple way to request website edits.

We like to use Markup.io as an easy way to share comments on our clients websites.  It requires an account (free) but you simply enter a URL and the platform creates a version of the page that you can add comments to. So instead of taking screenshots or trying to explain exactly what you want changed, you can simply add a comment in Markup.io and send the link to someone on your team to make changes.  There are other bells and whistles that let you do more if you need to.
