Has anyone tried hosting one? I'm talking about using the chest that is rewarded to you after you finish the Carnillean Rising quest. Basically you put any item in the chest, bury it somewhere in RS, and you can give away keys to the chest to players. The player then plays hot or cold by feeling the key and digs up the treasure with a spade when he thinks he's right underneath it.
I've had a bunch of smug players (even some high leveled ones that should know about the quest) report me and tell off some of the players that I got to involve in the treasure hunt and sometimes it gets on my nerves.
