How can I change my username?

I had signed up to test and had used my name as a username but after successfully pitching it to my colleagues I'd like to change the username. I'd rather change my username than sign up again and recreate my forms, so fingers crossed!

Hello,

We can change your username if the preferred username is available. If its already taken its necessary to choose a different one. Please let us know the preferred username so we can make the change for you.

Thanks.
