I don't see why you would need approval from CU marketing. You're an independent group of students.
CU has an annoying habit of sucking all the creative energy out of any organic fan movement. It's maddening.
Basically if the movement falls on its face they can tell someone else to fix it, but if it picks up steam they can make $$$$$$
I like "The Stampede" for the students
I also like what they are trying to do before tip off, getting people to bang on the chairs and make it sound like a stampede in the building, would be cool if the students could get it going in full.
