So I upgraded WordPress and upgraded Gallery, and the WordPress upgrade went great, but the Gallery update broke everything. So, no photos for the time being, until I get that problem sorted out. However, the site is now running entirely on WordPress (albeit highly modified). You can now comment on blog posts, but I’ve taken down the guestbook, since people were basically using the guestbook to comment on blog posts and photos anyway.
When the photos section is back up you will also be able to comment on individual photos.
