I know those still waiting are frustrated, but keep in mind that just because no one on Allnurses has had a change in status this week so far, that it doesn't mean no one has received a change in status this week. Allnurses is not the entire population of those who applied by a long shot.
Also, everyone is not notified at the same time because they have to manually change every status. That in itself takes time. The more people applied, the longer that will take. Different program have different people reviewing the applications, so they all hear back at the same time either.
Again, I know you're frustrated but this is how UMSON does things. I'm sure the riot on Monday didn't help either.
