Is it possible to have more than one person on this account?

If you meant to manage your forms and submissions, then yes.

You may consider our sub-account users feature, it would allow your forms to be shared/edited by other accounts.

Please do note that, subuser needs his own separate JotForm account and the number of subuser you can add will depend on your current plan.

You can check this article for more information.-How-to-Share-Forms-with-a-Sub-account-User

Please let us know if we can be of further assistance.
