"- Added faction messaging system. On by default. Use "~factionmessages off" to turn off, "~factionmessages on" to turn on. Type ".f <message>" or "/f <message>" to send a message that will only be seen by your faction mates, wherever they are."
Peopel will register fake characters and spam chat, listen important info or give wrong info for make ambush against enemes. I think this functions must be available only for accepted members more than 6 lvl. And don't speak, that you can switch off it.
