Updating username

Hello! In preparation of subscribing to a bronze account for our office, we're updating this account to a more general username. Can you please assist me in changing it from "amberdgraham" to "greenecenter". Thank you!

As requested, I have changed your username from "amberdgraham" to "greenecenter". 

Please note that if you are using custom URLs for your forms, it will no longer work as the username has been changed. You need to change the custom URL with your new username. You may check this guide: How to Create a Custom URL of a Form?
