Competition Competition

I need an idea for a competition to publicize the launch of a new online design magazine. The magazine is about all aspects of design and focuses heavily on the ability of the visitors to dictate the content.

I need you all to throw some ideas around for a competition for the launch. I need serious ideas please (all spam posts will be reported) and nothing overly complicated. The best idea ( if they are good enough) will be used and your site will be linked on the site. If there are a few good ideas I may sve yours for later but you will also be linked.
