"That's the thing, it doesn't take just one query to check all of this.  Each of the items the OP wanted to check lives in its own place in the database, and requires its own query to check.  And then you need to be checking permissions on each of those, because you don't want to be displaying posts an Admin makes in the staff forums to everyone else.  \nIf you're checking 10 different things, that's 10 queries, plus permission checks, plus any other processing necessary to do things like pull the person's profile picture and such, plus work to update the page in real time, all of this repeated every few seconds.  Your host would shut you down pretty quickly.\n"
