[Tex/LaTex] adding email under author affiliation

authoremail

How can I reformat the following so that it looks like below NAACL:

​%\author{Mona Jalal \\
%  Computer Science Department \\ Boston University \\
%  {\tt jalal@bu.edu} \\\And
%  Kate K. Mays, Lei Guo \\
%  Emerging Media Studies \\ Boston University\\
%  {\tt kkmays@bu.edu} \\
%  {\tt guolei@bu.edu} \\\And
%    Margrit Betke \\
%  Computer Science Department \\ Boston University\\
%  {\tt betke@bu.edu} \\}
\author[*]{Mona Jalal}
\author[**]{Kate K. Mays}
\author[**]{Lei Guo}
\author[*]{Margrit Betke}
\affil[*]{Computer Science Department, Boston University}
\affil[**]{Emerging Media Studies, Boston University}

Basically, I want to add {jalal, kkmays, guolei, betke}@bu.edu under the affiliation we all have the same domain.

Ours currently look like:

I modified the \affil command from the naaclhlt2018 package that you use to provide an email option, i.e. basically removed the counter display. I have not cleaned up the code, whatsoever.
