ConceptDraw is giving away for free their MindMapping software.
I’ve tried some online MindMap apps, but this one is full of features and you have lots of tools and more freedom on how to export your maps.

Quick note: Mind-mapping is a very helpful tool for people who rely a lot on their visual memory.

It is also the perfect tool to structure, organize and classify your ideas and information.

In order to get this software working, you need to register for a key right here: ConceptDraw MindMap full version offer, and then download the file for Windows or Mac – these are direct download links.

ConceptDraw MindMap works perfect on Vista.
