Hey, watchers hope you guys put this up in your journal as well.
If you look at the fine print for submitting your work into their competition. You actually assign all your copyrights to them forever. If that is OK with you then that fine but I just wanted to highlight that this is typical of a "rights-grab" competition. So be careful.
From their submit page
"Ownership of proposals and reproduction rights
The designers transfer all copyright and other intellectual or industrial property rights relating to his or her proposal. These rights will then become the exclusive property of the Organizers which will be able to use, publish or dispose of them as it sees fit, without geographical limitation or any other restriction, via all forms of printed (publications, posters, promotional material, etc.), digital (websites, multimedia presentations, etc.) and/or audiovisual media."
