I feel like that I should know this by now and that I might have known at some point, but at any rate: what does this number in the orange box indicate?
There is also a blue box that appears to its left that I find equally baffling. An explanation would be appreciated. (Comment: the blue box got removed, mods still have one.)
Well, now that the meat of the mystery has been solved, here's my next question: why are there so many fewer posts actually "awaiting review" than the box would suggest?
