Supress Contents frame in LaTeX beamer export

[Tassilo Horn <tassilo@member.fsf.org>]

Hi,

I've just did my first presentation with org.  Basically, it's pretty
impressive, but there are 2 things I could not figure out.

I use this setup in the org file:

--8<---------------cut here---------------start------------->8---
#+STARTUP: beamer
#+LaTeX_CLASS: beamer
#+TITLE: MOLA Opponent Review
#+AUTHOR: Tassilo Horn
#+EMAIL: horn@uni-koblenz.de
#+LaTeX_CLASS_OPTIONS: [presentation]
#+BEAMER_HEADER_EXTRA: \usetheme{Madrid}\usecolortheme{default}

* Slide 1

  Hugo

* Slide 2

  Hugo
--8<---------------cut here---------------end--------------->8---

1. How do I supress the contents frame?  I only have 1-star headlines,
   each representing a frame.  So there are no sections at all, and the
   contents frame is empty. :-(

2. In the PDF presentation, the lower left bottom line says

     Tassilo Horn ()

   What information do I have to provide to fill out the empty part
   between the parens?  I've thought that this is for the email address,
   but although I've added #+EMAIL: (which was auto-completed with
   M-TAB), it doesn't appear in the PDF or the LaTeX source...

Thanks for any pointers,
Tassilo
