My tool for this post is another very user friendly free web based tool. It is called Bubbl.us. You can find it at http://www.bubbl.us/ . Bubbl.us is a simple and free web application designed to allow you to create colorful mind maps /concept maps online. The maps can be embedded into your blog or website or can be emailed to your friends/coworkers or students. The maps can also be printed from the site.
For classroom application - you can give read only access so the maps can be viewed but not edited or Full Edit access which allows users to make changes and rename sheets.
