My friend created a user and password to edit the project so she thought she had an account. We later found out, because I had to transfer the site to her, that she didn't, and had to sign up again. If people sign up as Editor they should still be in the user database, this will:
improve user experience
avoid account duplication and multiple email/psw combination
more opportunity for webflow to nurture / upsell users who were added as editors
