title: Automatically Scroll Page from Top to Bottom, then Back Up (and Repeat)
body: <p>I'm trying to figure out how to, upon pageload, automatically scroll to the bottom of a page (which has been described sufficiently <a href="https://stackoverflow.com/questions/4621286/how-do-i-automatically-scroll-a-page-up-if-slidedown-goes-of-the-bottom-of-the">here</a>) and then scroll back up automatically upon reaching the bottom of the page. I can find the automatic scrolling to the bottom, but I can't figure out how to identify when I'm at the bottom of the page, and how to scroll back up when I am. I'd do this using generic Javascript (or JQuery).</p>
  
  <p>Thanks in advance!</p>
