At this point we're checking if we have a Webmaker account for the current logged in user - if we call the /user/ with an email and a get that doesn't exist we return a 400 (as you added yesterday) - and if we get a 400 that means there is no maker so we can show them the UI so that they can create a Webmaker account and become a maker!

We could make a secondary API point that checks and returns true/false but at this point it doesn't seem necessary.
