I have found software that I like at a site www.plangarden.com, but I want to know what others use.

I used paper, pencil and crayons for a long time, but I wanted something more sophisticated. plangarden does the trick, it is easy to use, inexpensive and does most of what I want.

I am sure that others may have found better software that I haven't. Please let me know what you use. I have asked this question on a few other forums, but I haven't found anyone that has found anything better.
