What a great service that allows you to focus on the other parts of getting your business live. Very easy process to follow and fun as well. I loved logging in to see the new entries each day.
Some tips for new users are to provide a strong brief to start, go searching in the logo store to see if there is a designer whose style you like. You may even find a logo that you can buy for $99 and modify.
I will come back and likely use my winning designer as I found him easy to work with, and he has a great eye for design.
