FreeMind - software that helps you think

With all of the reading I've been doing for my masters program I've had a craving for some kind of tool to help me collect data and synthesize material easily. At Westwinds we do a lot of stuff with mind mapping but I never had the software on my computer. I just nosed around on the web and found FreeMind. It's free and simple to use. Just wanted to share the jewel of knowledge with everyone.
