Thanks for comment.
You need to rank designs. Only first ranked designer can upload new designs now. You can change rank any time. After you decide on a logo, you can finish the contest finally.
I made the changes that you request. After you rank my design 1. , I will be able to upload a this new design. In that period, you can rank designs again and again. (If you have any questions, you can ask in forum)
Thanks
