We didn't mention Amused|Pepe- tag, which was my favorite. Faction had two members (obviously both deeply in love with my char) and lasted three days
Watching the player list while playing is really an act of metagaming, but almost all do it. Game also offers showing arriving/departing player option, rewarding us for even more metagaming. There were many pros and contras when we voted about it, so we decided to keep it. You might stop using it one day, to make the game more interesting.
