Just an FYI - My Webspiration is temporarily closing beta sign-ups on March 18th. It's highly recommended that you sign-up now so that you don't miss out on this opportunity. My Webspirtion is a free online graphic organizer/concept mapping tool/visual outline tool by Inspiration and is included in the UDL Tech Toolkit wiki under graphic organizers. I don't know of any other free online graphic organizers that allow you to easily switch from diagram view to outline view with one click. This is a must have as part of your Classroom Toolkit.
