JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
You cannot change your username in your end, but we can do that for you.
Please provide us at least 3 possible usernames you want (in case the first one is not anymore available).
For the email address in your account, you can easily change it under your account settings under the "Profile" section.
Do let us know how you would like to proceed.
