http://codex.wordpress.org/Inline_Documentation The page has inline documentation format standard and lines to open tickets that need to be worked on.

Hey, thanks for wanting to help, it is getting down to a shorter list of files to complete, but don’t worry about stepping on anyone toes. If you complete one function or 100, it will go a long way to completing the inline documentation sooner rather than the time I can spend on it.

Good luck.

I am very interested in helping with inline documentation for WordPress. If there is any more help that is needed, please let me know. Thanks!
