How do the sub users work?

can you help me understand the process for a sub user on the account to access a form i created on the main account?

Sub users can have access to the forms you share with them, you may select to share specific folders, forms or share all of them. You may also choose between share only forms, submissions or share access to both. 

Please note that sub users hold their own plan, for example,  if you're on the bronze plan and add a sub user to your account he will not be shown as bronze as well. 

Here is a guide that will provide you more details about sub users and how to share forms with them: https://www.jotform.com/help/232-How-to-Share-Forms-with-a-Sub-Account-User 

Also, note that there is a limit on the number of sub users you can add to your account and this will depend on the plan you have, you will find the limits per plan on our pricing page: https://www.jotform.com/pricing 

I hope this helps.
