This outlines all of the new changes made to the free site difftag.com. It now has a much easier to use interface, and easier to use tools. You can draw, collaborate, and socialize, all for free.

This set of video tutorials shows how to draw and collaborate on the free site, http://difftag.com. It covers everything from setting up your free account, to drawing and free specialty tools such as YouTube, Flickr and other widgets, to creating access settings for a free collaboration.

This site is so awesome! You can actually create graffiti on top of other pages on the Internet, and share them with friends. I have a feeling we'll be seeing some funny stuff on here.
