I really like the simplicity and the modern look of #19. Could we get an option with a lamp of knowledge at the top and possibly an option with the logo slightly larger in relation to the name? I think this is on the right track.
I also like that you have incorporated the mascot. Can you provide some additional options including the eagle or falcon mascot? We probably will not want that as a dominant feature in the logo but might. And we definitely will for our mascot logo. Might end up going with both of your creations...
