Hi 
A thread from the users list. There was a suggestion about writing some sort of
documentation for helping people write extensions so i gave them this link
http://wiki.documentfoundation.org/Documentation#Other_Documentation_and_Resources
They had already posted a bug-report here
https://bugs.freedesktop.org/show_bug.cgi?id=39998
and i have copied our list of external guides to that report too and also taken
the opportunity to invite more devs to join the docs team.
Regards from
Tom
