By posting your EQ designs, photos, and such on this site, you are allowing them to be used for reprint and further publication. From "Terms of Use"
"Visitor agrees as a condition of viewing, that any communication between Visitor and Website is deemed a submission. By making a submission, Visitor grants the administration and the owners of the Website a worldwide, non-exclusive, irrevocable, royalty-free, sub-licenseable and transferable license to use in any way, reproduce and distribute the submission and prepare derivative works of the submission without further permission. This includes commercial and non-commercial use of all submissions, including portions thereof, graphics contained thereon, or any of the content of the submission. Visitor agrees to only communicate that information to the Website, which it wishes to forever allow the Website to use in any manner as it sees fit. "Submissions" is also a provision of the Privacy Policy.
At the bottom of the Home page, you can find the links to the entire Terms of Use and Privacy Policy. I think everyone should have looked at these when they joined, but it never hurts to review the site rules.
