Can i change my user name after i sign up?

Or would it be better to sign up with a different account and create that user name?

Hello ursulaahern,

Yes it is possible to change account username but it can only be done by JotForm staff. Do let me know your desired username and if it is still available, we will change your account username. 

Please be noted that if you are using your form's custom URL, after changing your username the custom URL will not work any more since it includes account username in URL.

Thank you!
