#3 I like the scissors, and the border. But I don't really like the font so much, or the flames... I like the way you put the slogan at the bottom, though! I'm kinda leaning away from the use of fire in the logo.. I like the envelope, as well, and might want to see this incorporated into another design.
#6 I kinda like this. For some reason, it "looks" and feels like it's English! I would like to see what can be done by rendering the slips, themselves. How many ideas can you come up with, that have graphics that can represent the slips? (Hope you don't mind too much input on this).
