PRers might want to check out the mind mapping software, called MindManager, at
http://www.mindjet.com This is the software recommended by Tony Buzan of "The Mind Map Book." I've converted almost all my course notes over to mind maps. It makes everything seem much clearer.
The software has colors, symbols, and all sorts of goodies, and you can convert the mind maps to a web pages, power point slides, etc. if you want to make them accessible to others. Mindjet will give you a 50% discount if you are a student.
I have no association with Mindjet, except being a very happy customer.
