I want to create a prison, I do not know whether there is a plugin to create a prison, a simple plugin was not helpful, it uses the database, and I need that he had been without a database
goto Plugins and use the search bar......VOILA Jail Plugin http://forums.bukkit.org/threads/admn-jail-v0-6-1-jail-bad-players-714.1912/ Next time look
ahhh sorry didnt see the blue. ok You could use a zone plugin, set a zone deny entry or exit etc or you could create a teleport to a cell of obsidian. So if they mis behave type/tp jail. There are lots of them. Hope that helps.
If Home plugin supports permissions, you can configure permissions so that only select few people can use the teleport commands. You can make it so that normal users don't have rights to it.
