I don't believe I'm actually handling this properly, although maybe I am and it's the business model of Bitbucket, but what is the difference between adding (and paying for) "Users Access" and then adding users (and they don't need to exist in the "Users" section to the actual project permissions?
I suppose the simplest question is, I understand if I were to make actual "user" accounts I would/should pay for that. I'm hazy on whether I should be paying for all these individual project contributors that we add, who have existing Bitbucket accounts...
