Can I change my username?

You can not change username on your end, but we can do it for you. Please provide us three possible choices,as per your priority, in case that some username is already taken.  

Please note that if you are already using custom URLs on your form, they will not work anymore after making the change, you'll need to recreate your custom URLs again. But direct or default form URLs (the one having the form ID) will still be accessible and won't change.

Looking forward to your reply.
