Quoting the Tip of the Day "The GnuCash developers are easy to contact."
GnuCash has several mailing lists;
User List
<gnucash-user@gnucash.org> - User questions and discussions. The
developers and many very helpful users “hang-out” here.
Development List
<gnucash-devel@gnucash.org> - Discussion of issues related to the design and development
of GnuCash and submission of patches.
You can chat live with the developers on IRC! Join them on #gnucash at irc.gnome.org. Much more
at the GnuCash web site including links to WIKI and Bugzilla !!
