Adding a new contributor

I'm not sure exactly who you would want to contribute to the site, but if you want them to be able to do so, then you need to go to the blogger dashboard (what you see when you sign in; I think it will also display at http://www.blogger.com/home) and click on "Settings">"Permissions">"Add authors". Authors will, I believe, have permission to add posts, edit posts (but possibly only their own posts) but not to delete them. If you have an extra-special person who you want to make an admin (anything you can do, they can do) then you can do that from the panel as well. Currently, only my (Josh) account, the SWBC account and Simon's account are admins on the blog.
