I was just pointing out that "If your Design is selected for use by Threadless.com, you acknowledge that you assign to skinnyCorp LLC and its subsidiaries and affiliates (hereinafter collectively "Threadless.com") the entire right, title, and interest in and to the copyright in your Design including the right to sue for past infringement and the right to further sublicense the Design, for its sole and exclusive use on and in connection with the Items. You also acknowledge that you waive all "moral" rights that you may have in and to your Design." So submitting here when you're selling the same image on your site might be a conflict of interest. Not everyone reads the legal stuff in great detail.
