So basically I want the plugin to do this, because it's the only way to recognise it best. When people advertise IP's for servers, it's usually something with a sub-domain. Such as Play.bukkitPvP.net for example. Sites are usually something like Bukkit.org So can someone make a plugin where it recognises if it has 2 fullstops within words like a sub-domain and block it? Or is there a more efficient way, thanks. I want it to replace the fullstops with nothing if so.
