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
