Back in June 2004, Dab posted an article, Is selling your ideas a good idea?, about OpenAd.net starting up. Recently in the forums it was discussed as well.
Today I learned that OpenAd.net has teamed up with The Financial Times Creative Business section to launch a new ad competition. Once a month an ad brief is published and readers have two weeks to submit their entries at OpenAd.net. The first brief was put up yesterday and is for the Make Poverty History Campaign. You can view the brief here. They seem to have a decent list of judges too, including Peter Souter - CD from AMV BBDO and Greg Delaney of Delaney, Lund, Knox Warren & Partners. The winner will be featured in the next issue of FT Creative Business and on OpenAd.net. As always, read the legal for the contest if you're thinking of entering.
