Team development and different types of free trials?

I eventually found that I had signed up for some kind of organization integration portal account, when trying to sign up for a developer trial… I only figured this out when I went to the developer/documentation link, and it would present me a login again, and I’d end up in a login circle… What is the purpose of the two account types? Is there documentation somewhere that tells the story of Okta’s first principles? perspective? It is apparently different from the previous vendor I’ve looked at…

So now I have new account with a developer… I’ve created a Single Page App and authentication works… great… Now I need to get a team of engineers ( a couple more people ) to swarm on evaluation of this platform.

How do I add more developers to be able to work with the same application configurations and user sets?
