There are three "levels" of popcaps, and you can use them in any assortment you like: The "soft" cap produces a message on join, and takes no action. The "hard" cap disallows joining whilst too many other people are alive and playing in game, but allows observing. The "extreme" cap prevents people from joining the server at all while the cap is exceeded. It won't kick out people who failed to qualify during roundstart, but if they leave they won't be able to get back in. In each case a customizable message config option has been given. Admins are also immune to most population caps (they still are hit by the ones in job shuffling, but can late join as normal afterwards)
