#2 This is an interesting logo. Not sure the text will show up well in places where logo images are used like facebook fan pages or on blogs. Good for cards, but not letterhead. The learning concept doesn't really show, which may be the greatest issue.
#16 My advisor said "I think the learning font it hard to read. Also it would be nice to see this on solid white background. Maybe consider left or right aligning it?" THoughts?
Here is a revised version. I'm not sure how you want to show the concept of adult learning, since all of the usual symbols come from school (apples, rulers, chalkboards, etc.).
