[Tex/LaTex] put same address middle below authors names sig-alternate.cls

horizontal alignmenttitles

How do i make the university address appear below the authors names and in the center ? I need to do this because both authors are having the same address.

This is my existing code

\author{
\alignauthor Sean Fogarty\\
       \affaddr{NASA Ames Research Center}\\
       \affaddr{Moffett Field}\\
       \affaddr{California 94035}\\
       \email{fogartys@amesres.org}
% 6th. author
\alignauthor Charles Palmer\\
       \affaddr{NASA Ames Research Center}\\
       \affaddr{Moffett Field}\\
       \affaddr{California 94035}\\
              \email{cpalmer@prl.com}}%
}

There is essentially a solution to this posted on Dan Lazewatsky's latex page. Adapting it to your example you can write

\documentclass{sig-alternate}

\begin{document}

\title{Title}

\numberofauthors{2}
\author{
\alignauthor Sean Fogarty\\
       \email{fogartys@amesres.org}
\alignauthor Charles Palmer\\
       \email{cpalmer@prl.com}
\end{tabular}\newline\begin{tabular}{c}
       \affaddr{NASA Ames Research Center}\\
       \affaddr{Moffett Field}\\
       \affaddr{California 94035}\\
}

\maketitle

\end{document}
