Rereading the very old early parts of the Fishing thread that recently got necro-ed gave me an idea. Or maybe it's a modification of someone else's idea. Anyway, one suggestion in that thread was to have a way for players to collect autographs from NPCs, and to have a badge for getting them all, however many that is.
As a variant on that theme, what if every player-created toon could give and ask for autogrpahs from other PC toons? So like, when you're standing near someone in the game world, you can target another player avatar near you (within the distance you'd have to be to hand someone a pen or whatever, like melee range, but a little farther away is okay) and then click a temp power or something to ask them for their autograph. And then the target would get a pop-up window that asks them to select an option off a list, which options would be "Give Autograph, Deny Request for Autograph, or Trade Autographs". The Trade function being a quick way to simply give your autograph to the the other persona in exchange for them giving you one of their own. People could charge IGC if they want, and there could be different levels of badges for getting different numbers of autographs.
I would limit the toons that can give/request autographs to only level-capped characters, so as to avoid the problem of people making a bunch of toons just to pad their autograph stats, and I would make different NPC's give autographs only by unlocking them in carious ways. NPC heroes that give out task forces and other content might want you to complete the TF, or to complete multiple times in such a way as to have earned all the associated badges, etc. NPCs that show up in missions etc as "actors" (like Doc Quantum etc from the Alignment missions) could perhaps be able to give autographs if you do whatever you need to do to get them to give you one once you've finished the mission. The level-up contacts, if they're caped heroes or "famous" in the game lore, could give you their autographs upon request once you reach the level cap, but not before, etc.
I would want to avoid having any efficient way to collect or distribute autographs in any massive sense, I would make it a strictly person-to-person, face-to-face, one-at-a-time process with no possibility of doing them by email, and no way to trade your autograph of UberDude to someone else once acquired. You'd have an "Autograph Book" window with tabs etc showing your total numbers and whose autographs you have already, with tabs for NPCs and PCs, etc.
This way, once someone dings 50 or whatever the cap is, everyone will immediately want your autograph to add to their collection. You could make announcements in Broadcast like "I just hit 50!!! Come to Atlas Park, I'll be under the statue singing autographs for my ADORING fans for the next 30 min!!!" etc
