There are many sites that offer lessons on-line. But most of those do not offer a course that makes sense, so I recommend trying an on-line community where you can chat with guitarists of all skill levels and learn from them. My Favorite is: http://www.weplayguitar.com/user.php?op=register&module=NS-NewUser&refid=1090

You can also try some of the following websites:
http://www.ultimateguitar.com/
http://www.guitartricks.com/welcomeH.php
http://www.learnlicks.com/
http://www.riffinteractive.com/ – Very cool site

I hope that this helps. Nothing replaces a live instructor, but these are some of the better sites that I have found. Have fun and keep practicing.
