A: Hey Michael,

The number of users allowed on an account will be updated with the next platform release, which will happen in the next few days.

"Users" will have their own login to your account and you can control their level of access. For example, you could allow them to see only a single app in the account and have limited editing capabilitites. You do this through the role-based access control feature. The easiest way to do this it to set up a role that allows access based on a "tag match". You then tag the user and the apps and actions you want the to see when they log in. They will see everything that has a tag matching their tag.

Hope this helps.

Cheers!
