Currently, in the Manage tab of one's profile, there's an entry in the log for when the user was approved, but there should also be one for when the user was created:
{F3904861}
After discussing this with @valerio.bozzolan, it seems like the issue is that creating a user does not currently employ a transaction (xaction). So it might be necessary to create a new transaction in [[https://we.phorge.it/source/phorge/browse/master/src/applications/people/xaction/|src/applications/people/xaction/]], and/or modifying [[https://we.phorge.it/source/phorge/browse/master/src/applications/people/controller/PhabricatorPeopleNewController.php|controller/PhabricatorPeopleNewController.php]] to use transactions.
