It does indeed still target staff usernames directly rather than the staff group. I agree it would make sense to target the staff group instead.
I’m actually experiencing an odd issue with this message on my neighborhood forum at the moment. I am getting the “1 user waiting for approval” message regularly, but when I click the link to go to the review queue there is nothing in there. I do have the must approve users setting enabled. I’m not sure what to do to make this go away.
I think we intend to “roll up” multiple notifications like this instead of displaying a list of them. Here’s how my notifications looked this morning.
While troubleshooting (1) I looked in the messages for staff on my site (I have 3 moderators including myself) and they all have a list of these messages in their inbox. But when I look at each individual message I see there is an odd mix of recipients. Sometimes it’s just one moderator, sometimes it’s two moderators, and sometimes it is all three of us.
