hello!
my concept is as complicated as it is simple :) the mark is composed of two elements: the first is a lightbulb wich i know is kind of overused but i added a twist to it and that is where the second element comes into play: the green part actually forms a question mark if you look carefully
so the mark itself would be described as " an answered question" - your site answeres questions(linked to the tutorials that your website offers)
i added a version with green and yellow and one with blue
check them out and tell me what you think!
waiting for feedback,
Mircea
