title: Ruby on rails super simple signup page
body: <p>How would I be able to make a signup page with ruby on rails?</p>
  
  <p>Like, I have a beta page and a user enters their email address and then I can add it to the database.</p>
  
  <p>Also, I could send them an email confirming their signup</p>
  
  <p>EDIT: I want something real simple.  Like, just plain adding a row in a database simple.  I don't need a password box and a username box because that just further complicates things.  I'm a beginner so I like to have things simple.</p>
