I was thinking that, while he's been the developer with the most facetime in the History of MxO™, and aside from penning all the story material and more after Mr. Chadwick abandoned us, Mr. Chamberlain doesn't have a "signature" in the game. The other developers will always have their avatars and such to mess around in the virtual world, but how will Rarebit be remembered? Through an update which holds a bunch of NPC masks? Please.
I propose a randomly placed billboard. I got the idea when I googled my name and rediscovered this on a French MxO fansite:
It's my entry from the long-dead billboard contest held back in I have no idea. All I remember is that I got a free shirt and a copy of the game out of it, and I think a free 30-day subscription card too. I still have that shirt.
My idea is probably foolishly vain. I'm sure that Rarebit has some elaborate server-crashing plan for his last day for us to remember him by, but I just thought... how about one from the fans?
