How customizable is sign up form on Webflow

Hey Community,

The main issues are;

  1. Do we own the content and can we transfer it when we want?
  2. How customizable is sign up form?
  3. Can we keep send different forms and have them under one database?
  4. Can we build one back-end algorithm that pulls and calls people to the main database in order to tailor the content for the user? Because we want to create course curriculum based on our student’s profile and their knowledge. (API call)
  5. Does MailChimp has API algorithm so we can send different messages on based who they are?

I would really appreciate if somebody could answer my questions. Thanks!
