Minwah was invited. As for content, there's plenty more that I can / will add, but I don't have much to offer in the way of introductory stuff. The most logical thing to add before it goes live, is a short description about making your own cabinet, and links to a beginner guide, then a short note telling people they can and should edit the pages with a link to a digest help page (rather than the full wiki site)
I don't have any comments about the navigation per se... just a shame that it has to look so off-the-shelf wiki like... especially with such a visually rich hobby as the one we have.
I do think that the help section should have basic WIKI stuff added to it before the site goes live. I know there's a whole site dedicated to wikiness, but the basics should be on that page.
Also "random page" is just silly chartjunk navigation, and community portal should go to the board rather than the BYOACWiki:Community Portal page.
