I noticed on the Getting Started Guide that I should create a Functional Account. Why shouldn't I create a personal account?
We strongly encourage the use of Functional Accounts because they aren't tied to an individual. That way the account can be shared with many people on a team. And, if someone is on vacation, then the team will still have access to make updates, monitor usage, or fix issues.
Of course, having an individual account for Testing and Proof of Concept work is also very useful. In that case, please feel free to request an individual account. But, please understand if we ask why you would like an individual account before approval.
