title: How to add more 'owners' to a gem in RubyGem
body: <p>I want to add a new <em>owner</em> of a gem in RubyGem but I don't know where I should do this:</p>
  
  <ul>
  <li>in the .gemspec?</li>
  <li>in any place in RubyGems.org page?</li>
  </ul>
  
  <p>I have tried to use the <em>gemspec options</em>:</p>
  
  <ul>
  <li>s.authors</li>
  <li>s.email</li>
  </ul>
  
  <p>But still not seeing my <em>co-owner</em>.</p>
  
  <p>For a concrete example I'm trying with this gem:</p>
  
  <ul>
  <li><a href="https://rubygems.org/gems/evax" rel="noreferrer">https://rubygems.org/gems/evax</a></li>
  <li><a href="https://github.com/SponsorPay/Evax/blob/master/evax.gemspec" rel="noreferrer">https://github.com/SponsorPay/Evax/blob/master/evax.gemspec</a></li>
  </ul>
