One of c.u.c’s historical goals has been to recruit new participants to Ubuntu teams.
A link to the many ways to contribute to Ubuntu should be more prominent on the landing page. Currently, the many fine “Contribute” posts are not visible on the landing page, but are buried two directories down, within “Documentation/Contribute”.
Many top-level topics/teams currently lack a posting or sticky with an appropriate how-to-contribute post (or link).
