Hmm, nothing makes me more excited than to find a great tool to use with my writing. I'm working on the third chapter book in my series and after using all different types of ways to keep my plot and subplot clear, I found a blog by Nancy I. Sanders with an excellent plot outline graph. AND YOU CAN PRINT IT OUT AND GET STRAIGHT TO WORK. Lots of other tidbits of good stuff here also.
Don't I just feel on top of the world.
