	Kathleen Sundmark almost 4 years ago	Great info. Lots of work. Thank you for these maps. They represent a lot of information and a great deal of work.

	Edward Shekhter almost 4 years ago	Re: Great info. Lots of work. Thank you. Just got NovaMind about 3 weeks ago. This is my first go at it. There is so much information, but I am not sure if the way I presented/did this is the best way. Also I am looking for more insight and better way to do these mind maps, from experienced people.
