I think this is recently introduced, though it's possible I just haven't noticed until now. But when I open the little dropdown window for my PMs, all of the avatars are the avatar of the last person who sent a PM in any of my conversations. So if it was me, all of them show my Klackon. If it was instead, say, warban, you get the bouncing pony. Which frankly, is kind of obnoxious, seeing 5 of those.
Self-righteousness is incompatible with coalition building.
Same here - Variable is all of my icons on the PM dropdown.
Let's play Mario Kart or something...
