I have reached my limit of 25. What do I need to do to be able to create more forms?

I just tried to clone a form and it said I have reached my limit of 25.  What do I need to do to be able to create more forms?

You have reached the limit of 25 forms that are offered for Bronze plan. You can upgrade to Silver plan which allows 100 forms. Please check our Pricing page for more information about plans. 

Or you need to delete your actual forms so you can create new ones. Note: If you delete your forms make sure you download the backup of submissions for those forms.
