Sends greetings in chat when you join someone or when someone join you, it will also ask if it's safe to join on stealth heists.
Messages are picked randomly from the three .ini files included, which can be modified to your liking.
motd host.ini - Shows messages when you are host. motd client.ini - Shows messages when you are client. safe message.ini - Shows messages when you are in briefing, host is in game, it's a stealth heist and you are not host.
Note:
In the files you can use $NAME to specify where the players name will appear in the message, example is in the image attachment here. It also wont message players that are in the ban list.
