ArcGIS Online allows an organisation to specify a required username format (i.e. firstname.lastname).
When we manually invite users, we have to adhere to the underlying ArcGIS Online rule.
However, when our users sign-up to our hub initiative (via the sign in widget) there are no controls on their username format.
This makes it more difficult to support our users, undertake account management and represents a business risk as the user may select an inappropriate user name.
Ideally, the sign-up widget would allow us to control the username of members. This would allow us to configure the username, for example, including their primary imitative:
<initiative name>.<first name>.<last name>.
At a minimum, the automatic sign -up processes should respect the underlying organisational AGOL settings.
