title: Side-by-side institutes in latex beamer title page
body: <p>On the title page of my Beamer presentation, I have three authors, from two institutes. The authors get listed side-by-side, which is fine. Less fine is that the institutes get listed one on top of another in an oddly bulky column down the center. In other words, I get this:</p>
  
  <pre><code>                 My Talk Title
  
  John Foo (1)     Sarah Bar (2)   Isaac Foo (1)
  
                  Foo University
                  Foo, MA, 02134
  
                  Bar Institute
                  Bar, CA, 90210
  </code></pre>
  
  <p>Whereas I'd love to have this instead:</p>
  
  <pre><code>                 My Talk Title
  
  John Foo (1)     Sarah Bar (2)   Isaac Foo (1)
  
      Foo University         Bar Institute
      Foo, MA, 02134         Bar, CA, 90210
  </code></pre>
  
  <p>Any suggestions would be greatly appreciated.</p>
  
  <p>EDIT: here's the code I'm using:</p>
  
  <pre><code>\documentclass{beamer}
  \usetheme{Warsaw}
  
  institute[Foo and Bar]{
    Foo University\\
    Foo, MA, 02134
    \and
    Bar Institute\\
    Bar, CA, 90210
  }
  
  \author{John Foo\inst{1} \and Sarah Bar\inst{2} \and Isaac Foo\inst{1}} 
  \title[My Title]{My Talk Title}
  
  \begin{document}
  
  \begin{frame}[plain]  % 'plain' suppresses header &amp; footer decorations
    \titlepage
  \end{frame}
  
  %% .. rest of presentation goes here
  
  \end{document}
  </code></pre>
