Tom,
We are aware that some may be somewhat intimidated, and we are focusing on making this fun and educational at the same time. I mean, even around here, one of the cruelest questions is "So, what would you design?" Everyone loves critiquing, but no one loves it when incoming......... Although, if this is to be truly realistic maybe a short course in accepting critiques should be among the topics.
While the attendees will have some real design challenges, being slapped on the wrist with a ruler will not be one of them, at least not[size=78%] [/size]for the poor guys/gals who draw me as an instructor.
