I am deadly busy these days with some works, and there is always an open instance of FreeMind on my workspace. If you haven’t used this Mind Mapping tool yet, just use it for one time, for any subject you wish.
Today, I was talking to a friend and ( lol ) there is a mind map of Different Type of Kiss Here !!!
You can find the FreeMind version of this scheme here, please let me know if you have done any modification on it.
