Help With Coding:
You can join Choqok development mail list to have a discussion on development or other stuff with Choqok developers or people interested in its development.
And some useful information about how to write an special Plugin for Choqok is available at gitorious wiki pages.
Choqok’s source code is hosted at KDE git repository, to have commit/push access you need to have a kde git account. Check this for more information.
For coding, I recommend kdelibs coding style for Choqok. Nobody is forced to use it. but to have consistent formatting of the source code files it is recommended to make use of it.
