When someone registers on the Paratext website the request is sent be approved by one of the organization approvers. (SIL has people in each Area who can approve users in that area. Other organizations have their own approvers)
When “Joe Bloggs” requests a registration his request is checked to see if he qualifies under the organization. If there is a question about who he is or whether he should be approved then the person doing the approving should check with the entity for more information. The request might be approved, declined, or forwarded to another organization for approval.
Once “Joe” is approved then an email is sent out to the address listed as the user address. I believe an email also goes to the address in the completed by. It is very important that when the user receives a message asking them to confirm their email address - that they follow those instructions. If that person is unable to do that step then it is better to use the completed by address for the user so that the address is confirmed. If the email address of the user is not verified then the account is removed from the Paratext database and the process must start over.
Paratext does not know who the Administrator for Joe is so it can’t send any information to that person. There is a place where project is tracked, but people enter that information in a variety of ways.
All of this will change when Paratext 8 is released - I’m not sure of all the details so that will have to wait.
