The MRTG web site, http://www.mrtg.org, offers a great deal of
information and help. You can subscribe to the MRTG mailing list from
this page. MRTG is also discussed frequently in the Usenet newsgroup
comp.dcom.net-management. Finally, don't
ignore MRTG's documentation, which is located in the
doc subdirectory of the MRTG distribution. The
documentation is included in both text and HTML form and is fairly
complete and comprehensive.
