As a Davidson student, you have access to a library of professional templates (i.e., StudioPress and Organic Themes). This site uses a StudioPress template called “Whitespace Pro.” There are also many free templates that you can download off the web – search for “wordpress themes.” You should probably pick one of the ones from Davidson’s subscriptions, but here are some free ones that are pretty good to start with:
http://wordpress.org/themes/zalive
http://wordpress.org/themes/customizr
http://wordpress.org/themes/mesocolumn
http://wordpress.org/themes/zeedynamic
http://wordpress.org/themes/travelify
http://wordpress.org/themes/responsive
http://www.freethemeforwp.com/themes/skeleton/
You can switch back-and-forth between themes, if you want; the content (posts, pages, uploaded media) will remain the same.
