Hello, Ian! For your convenience, I'm going to post the "Contest Holder Guidelines for Posting" that are at the bottom of each contest page (yours included). It states:
"We require that you do not ask one designer to use elements or concepts from another Designer. The general rule is that, if a Designer was the first to submit the idea, they essentially own that concept or idea for the remainder of the contest. Requests or ideas you have put in your contest Brief are fair game and open to everyone. Concepts that are considered obvious will also be fair game, for example: a dog & cat for a pet hospital, shopping bag for an e-commerce company, a tooth for a dentist, initials for a lawyer, etc. "
Please edit your comments above to no longer request Designers use the same concept that jesicastudio submitted (#6). Keep in mind: this is a contest site; we are not all getting paid together -- it's all of us submitting our own concepts to win your business. Please regard us as competitors, not a team -- we're a community, but competitors nonetheless. We don't all work together and share ideas between ourselves. :)
If you have any other questions, please hail Admin via the "Help" link in the upper right-hand corner. We thank you for understanding in advance.
