How to remove the branding?

I have a few questions: 

1. What do I need to do to remove the jotform link at the bottom of my quiz? Do I need to upgrade?

1. Yes, branding can only be removed on paid accounts, you can do this upgrading to any plan, once you have upgraded you can turn off the branding on your account settings, here is the direct link: https://www.jotform.com/myaccount/settings 

We recommend to ask one question per ticket, this way we avoid confusion while discussing multiple matters, we will assist you with your other questions here:

Thank you. And I understand about the confusion of asking multiple
questions in one email but it might serve us customers better if you
offered chat customer service especially for paid accounts.

We indeed provide chat support, this is available between 9 AM to 7PM in EST time and as long as we do not experience too much traffic on our support system, which is the current case. If chat is available, you will find the option on My Forms or Pricing page. 

Thanks.
