For those of you already thinking about/working on the creative brief for Project 2 (and good for you!), I have posted to the Documents page a slideshow Chris Stadler put together to explain a CB format. There is also an example in your book (page 53).
I would prefer if you use one of these two formats, which are very similar. I will discuss creative briefs in class next Tuesday, but feel free to email me with any questions before then.
