If you didn't already receive this brochure in the mail, Drexel University is sponsoring a photography contest for high school students. The Deadline is 12/08/07. The fee is $20 per person for up to 3 entries. I emailed them and they do accept digital photography (the brochure didn't specify darkroom vs. digital). Each photo must be matted with the form on the back.
