What about, if the forum gets a new post and if it wasn't uploaded, we can see a number in the text showing how many post are waiting for beind read. Every time you upload (or when you read them), the number is reseted !
A perfect example is (copyright warning):
It could get a good use out of it but by that, any admins and mods needs to check on every single posts that has been posted with that kind of permission and also the regular users needs to wait until it gets revealed which can take time for sure. Honestly this is a huge mixed feeling about utulising this permission in this place since peoples can be impatient about posts that aren't revealed for a day and it can be quite troublesome so I'd rather not change permissions that permits like that that let's the admin and mods more work just to get it done.
Honestly this is pointless. You can see the unread posts here and you can see if someone is making a post by viewing who is online. This function would be generally useless, too.
