[557]51  People from all around the world are already helping.  There are
52  probably ten people who do not always post to the discussion mail list but are constantly
[554]53  "improving" the code by demanding performance or bug fixes or enhancements.  And there
[557]54  are others posting questions to discussion groups. (JF 04/01/05)
55  </p><p>
56  A good start is to join the coin-discuss
57  <a href="" target="_top">mailing list</a> where CBC is discussed.  Some
58  other possibilities include:
59  </p><div class="itemizedlist"><ul type="disc"><li><p>
60  Comment on the design
61  </p></li><li><p>
62  Give feedback on the documentation and FAQs.

64  Break the code, or better yet -- mend it.
65  </p></li><li><p>
66  Tackle any of the "to-dos" listed in the Doxyen documentation and contribute back to COIN-OR.
