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.
I have checked your account and there are two usernames associated to your email address. One of which is dormant. Although I believe that the username you are using right now is the one similar to the domain name of your website? Also, as I'm not able to find any JotForm-related form in your web page.
However, I do not see any problems with your account and the forms seem to be working properly. Have you tried retrieving a password for your account from the login page? You can try going to this URL and click the Forgot password link below the text box: http://www.jotform.com/login
Please do keep us posted if you have questions or if you need assistance.
