A discussion in xgame came up about using @temp_place and sitting since sitting overrides temp_places. Staff chimed in that temp_places should not be used for sitting as sitting provides actual mechanical benefits to potential attackers so making it look like you are sitting (and thus more vulnerable than you actually are) is metagaming and not allowed.
This sparked the discussion about a sit_place command to allow custom sitting in rooms that mechanically function as sitting rather than temp_place which functions as standing.
Figured it'd be good to have the discussion here so it's not lost.
