A: You can sign up for only one primary org with the one email say ramesh@astravue.com.

However, to be part of another org you need to be invited to the other org which was signed up with another email say ramesh@acme.org.

The roles of ramesh@astravue.com can be updated accordingly for the new org. See below

However, I will be frank on one fact. Managing the task and notification is kind of manual as there is no way to show them as one consolidated view.

I have plans to update this feature but that will be taken up later.

Ramesh
