LOL , more than happy to help
next to your :iconETIKATE-STYLE; icon there is a lot of information right ? in the right side you will find something called "Submit Art" click on it .
try to discover the page your self because that will help you
the most important thing you need to know in that page is about the category ! if you are gonna submit a design , the category should be : Designs & Interfaces > Miscellaneous
and if you have any question get back to me , i don't mind <3
