Hello, I just want to point that one of the tools that I am using fervently XMind Pro (http://www.xmind.net/pro/ ) is available this week for half price here: http://www.reducto.info/2009/02/do-not-miss-xmind-pro-3-year-subscription-for-just-6450-50-discount/ I am a big fan of XMind so I was thinking about sharing this information with you. Also there is a free (open source) version of the XMind that can be used. Enjoy!
