As I was installing AddThis Sharebar on Tumblr, I figured I’d just do a quick screen cap. There’s really no instructions in the video. This is just a screen cap that shows how quick and easy it is to add sharing tools on your page. I actually added the Sharebar to 6 or 7 of my Tumblr blogs. Watch the video to see how I did it. Enjoy! (get your own sharebar at: http://www.addthis.com/labs/sharebar)
