When you are submitting a design for the first time, you may receive an error message while trying to create the 'designer URL' that will become the URL to your designer profile. If the site isn't letting you choose a certain URL, that means either that it’s already taken and you’ll have to choose another or that it includes an illegal character. Numbers and non-alphanumeric characters (like question marks, exclamation marks, ampersands, etc.) will not work in your URL. Please pick another one and try again!
PLEASE NOTE: To create your URL, you should only type in the words you want to follow "www.minted.com/designer/". For example, if I were creating an account for My Awesome Artwork, I would just type "myawesomeartwork" in the blank field.
