Perhaps this is just me, but I'm one of those people who gets bothered when things aren't all the same across the board.
Like, for example, the "Support Us!" banner in the Credit Shop. The art used is obviously from before the Mirabilis redraw, and it doesn't fit in with the rest of Res' updated site art. It actually makes the CS feel a bit sloppy.
There's a few other things I've noticed, too- like when you update your signature preferences, the notification spells it "signiture." Somewhere else on Res (I forget where) the wrong form of 'your' is used.
I'm not sure if the staff is actually in progress with fixing these already or if they just slipped through the crack, but perhaps they could be corrected? It gives an awesome site a more lazy feel otherwise.
