title: Populate URL Parameter with Logged in User Name
body: <p>How to populate an url parameter with the user name of the person that is logged into my site?  For example: in the url 
  <a href="https://www.example.com/somethinghere?sid=" rel="nofollow noreferrer">https://www.example.com/somethinghere?sid=</a>   I am needing to find a way to populate the username of the person logged in after sid.  So let's say my username is <strong>bigred</strong> and I'm logged into my site, how do I go about having the url show <a href="https://www.example.com/somethinghere?sid=" rel="nofollow noreferrer">https://www.example.com/somethinghere?sid=</a><strong>bigred</strong>   </p>
