So... Gmail has this constantly increasing storage space ticker showing how much space they give you. It's up to 2846 MB currently. And two of my accounts show that. The one I use most says "You are currently using 97 MB (3%) of your 2846 MB." All well and good.
But I just logged into one of my others (that I obviously rarely use) and it says this:
Hmmmm. Error? Sign of a pending change? Random weirdness? No idea, but that is a LOT more space. Just thought it was interesting. I logged out and back in to make sure (and take the screen cap) and it was still there.
