<LI>If you find a bug, <AHREF ="Section_errors.html#9_2">this section</A> describes
how to report it.
<LI>If you publish a paper using LAMMPS results, send the citation (and
any cool pictures or movies if you like) to add to the Publications,
Pictures, and Movies pages of the <AHREF ="http://lammps.sandia.gov">LAMMPS WWW Site</A>, with links
and attributions back to you.
<LI>Create a new Makefile.machine that can be added to the src/MAKE
directory.
<LI>The tools sub-directory of the LAMMPS distribution has various
stand-alone codes for pre- and post-processing of LAMMPS data. More
details are given in <AHREF ="Section_tools.html">this section</A>. If you write
a new tool that users will find useful, it can be added to the LAMMPS
distribution.
<LI>LAMMPS is designed to be easy to extend with new code for features
like potentials, boundary conditions, diagnostic computations, etc.
<AHREF ="Section_modify.html">This section</A> gives details. If you add a
feature of general interest, it can be added to the LAMMPS
distribution.
<LI>The Benchmark page of the <AHREF ="http://lammps.sandia.gov">LAMMPS WWW Site</A> lists LAMMPS
performance on various platforms. The files needed to run the
benchmarks are part of the LAMMPS distribution. If your machine is
sufficiently different from those listed, your timing data can be
added to the page.
<LI>You can send feedback for the User Comments page of the <AHREF ="http://lammps.sandia.gov">LAMMPS WWW
Site</A>. It might be added to the page. No promises.

<P>LAMMPS development has been funded by the <AHREF ="http://www.doe.gov">US Department of
Energy</A> (DOE), through its CRADA, LDRD, ASCI, and Genomes-to-Life
programs and its <AHREF ="http://www.sc.doe.gov/ascr/home.html">OASCR</A> and <AHREF ="http://www.er.doe.gov/production/ober/ober_top.html">OBER</A> offices.
</P>
<P>Specifically, work on the latest version was funded in part by the US
Department of Energy's Genomics:GTL program
(<AHREF ="http://www.doegenomestolife.org">www.doegenomestolife.org</A>) under the <AHREF ="http://www.genomes2life.org">project</A>, "Carbon

<P>If you use LAMMPS results in your published work, please cite the J
Comp Phys reference and include a pointer to the <AHREF ="http://lammps.sandia.gov">LAMMPS WWW Site</A>
(http://lammps.sandia.gov). A paper describing the latest version of
LAMMPS is in the works; when it appears in print, you can check the
<AHREF ="http://lammps.sandia.gov">LAMMPS WWW Site</A> for a more current citation.

<P>If you send me information about your publication, I'll be pleased to
add it to the Publications page of the <AHREF ="http://lammps.sandia.gov">LAMMPS WWW Site</A>. Ditto
for a picture or movie for the Pictures or Movies pages.

<P>The core group of LAMMPS developers are at Sandia National Labs. They
include <AHREF ="http://www.cs.sandia.gov/~sjplimp">Steve Plimpton</A>, Paul Crozier, and Aidan Thompson and can
be contacted via email: sjplimp, pscrozi, athomps at sandia.gov.
