Check out the Mission Federal Credit Union site redesign/rebuild. This site was "converted" (actually completely rebuilt from the ground up) to a drupal site from a sharepoint site. WOW! That was fun. The design is more modern and content maintenance drastically improved. Drupal makes it easy. There are several sub-sites and a teen checking site at Missionfedmpower.com. I also designed an internal "portal" for Mission Fed that hosts all the manuals/procedures and internal communications of the credit union.
