The "More" link on the homepage just points to the main page for the docs. This makes it completely pointless except to fill in some extra space on the homepage.
Perhaps this could be changed to something else. I am thinking since a Q&A question came up about how to support WPD either at a conference or as an individual. That way people who want to help talk about WPD and/or get others involved in helping can have somewhere to get a food good ideas. I think that could be a good fit for a link on the homepage in place of the currently (seemingly) useless one.
