Online Resources I use on a regular basis

http://www.digital-photography-school.com/
http://www.guardian.co.uk/artanddesign/series/camera-club
http://www.pixelinduced.com/
http://photography.about.com/

All of these sites include educational articles, a community of photographers (amateur and professional) and contests (which encourage me to get out there and try new things).
