Gallery2 integration works, mostly. Well the sidebar and full page embedding works, more to come. Activate WPG2 by pointing it to http://stjschool.org/gallery2/ and it should autodetect the rest. Then place the STJ Galley widget in your sidebar.
Subscribe2 allows you to email, automagically, site updates(a new post for example) to your subscribers. A new Subscribe link appears in your footer.
