My post about putting "the" in front of French road/boulevard/bridge/roundabout/arcade/palace names resulted in a full explanation from former MUD2 arch-wiz Henry Mueller regarding when to use them and when not to, and also when to capitaluse rue/boulevard/pont/rond-pont/gallerie/palais (basically, only at the start of a sentence). This led to so many changes that I'm going to have to re-read everything through once more in case I find some other example of French street names that I've missed.
I am somewhat regretting my decision to make the book longer in response to pacing problems, rather than shorter.
