title: Using email address as route parameter
body: <p>I'm trying to use an email address as a route parameter. When I first click the link, the page loads fine, but when I try access the url directly I get the following error:</p>
  
  <p><code>Cannot GET /users/edit/susannaallison%40emergent.com/</code></p>
  
  <p>This is an example of what I'm trying to use:</p>
  
  <p><code>http://localhost:5555/users/edit/susannaallison%40emergent.com/</code></p>
  
  <p>I know it has to do with the <code>.</code> in the email, but I'm trying to find a way around that.</p>
