Thanks for getting the ball rolling. I like the emphasis on the chapter name by making the Akron large and the national organization name small. I like the blue and I like the purple, with a white backgroung they look good not sure how they would transfer to anything other than white.
The tree is a nice idea ... has a certain "authenticness."
#6 and #7 made the blue lighter and purple is bit lighter too. what it gives is that ifusing on a dark background (black here) it will work better. dark logo on a dark backround is not good to use
