@wwtamu : Could you please add a small description to this PR? We really shouldn't be merging anything that just has "template text" (as it's not useful to others who stumble on this PR later). :)

Hi @tdonohue, I've updated the issue text since @wwtamu and I were discussing this on Slack today and I suggested he file the issue. Thanks @wwtamu!
