To change your folder name or username, please log into your account at:  http://ViralURL.com/login.php

Now click on your name or Avatar image left of the logout button at the top of the dashboard.

On the next page you will find the "Change Folder Name" link.

From there you can edit your designated user name which will also be used in your affiliate and cloaked inks.

Note: If you change your folder name your referral URL as well as all your cloaked URLs will change as well. Also, if you use "Advanced Cloaking", make sure you update that as well.
