Our detectives are back with the following intel on this WordPress site
The site is using two themes, one child and one parent. The child theme is based on the parent and often custom to the site. The parent theme is Twenty Eleven theme by the WordPress team .
We could identify 3 plugins (there might be more) - All-in-One Event Calendar , TW Pagination and Twenty Eleven Theme Extensions
The 2011 theme for WordPress is sophisticated, lightweight, and adaptable. Make it yours with a custom menu, header image, and background -- then go further with available theme options for light or dark color scheme, custom link colors, and three layout choices. Twenty Eleven comes equipped with a Showcase page template that transforms your front page into a showcase to show off your best content, widget support galore (sidebar, three footer areas, and a Showcase page widget area), and a custom "Ephemera" widget to display your Aside, Link, Quote, or Status posts. Included are styles for print and for the admin editor, support for featured images (as custom header images on posts and pages and as large images on featured "sticky" posts), and special styles for six different post formats.
