E-mail us at email@example.com with your current username, and what you’d like to change it to.
Please keep in mind that changing your username can affect your placement"in our search results as well as on Google search. We do not advise multiple username changes. Also, remember - a username cannot begin with numbers or contain special characters. When a username starts with numbers, the rest of the account gets bent out of shape (especially the uploader).
Remember, your username shows up in your URL and on your storefront, so make sure it's the name you'd like your audience to see!
