Wisemapping is a mind mapping program.  A mind map is a diagram used to represent words, ideas, tasks or other items linked to and arranged radially around a central key word or idea. It is used to generate, visualize, structure and classify ideas, and as an aid in study, organization, problem solving, and decision making.It is a lot like Inspiration but you can attach documents to it online, and share with others online.

The program is only good for Internet Explorer and Firefox, it does not work with Safari so beware.  You also need to register and receive a verification email to activate your account, so it does take time to set up.  You need to wait for your verification email.
