I'm working on a Google Summer of Code project that will be working on an extension called BookManagerv2 (http://www.mediawiki.org/wiki/Extension:BookManagerv2). This extension will allow users of wikis that host book content to structure the books. This structure will then be used to create navigation bars, and eventually add more functionality. I'm still waiting on a Gerrit repository, but wanted to get this request in now to minimize any delays.
The component should be added under mediawiki/extensions. Raylton P. Sousa (firstname.lastname@example.org), Matthew Walker (email@example.com), and myself (Molly White, firstname.lastname@example.org) should be added to the default CC list.
