Why is my form disabled?

I checked your account and your Abbreviated Registration Form requested usernames and passwords.  We do not allow for the collection of such data through forms.  As per our terms of use:

Collecting Sensitive Information. You may not use the JotForm to collect certain types of sensitive information, including but not limited to credit card information and any type of login credentials. You may collect some sensitive information such as social security numbers or driver’s license numbers, but you are required to use best security practices of JotForm including SSL and Encrypted Forms features.

I removed the username and password fields from your form and activated your account.  Your forms should be usable once again.
