Yea I like Justice suggest command it should be /ssmotd to easily memorize the command. I like your suggestion because it will help the squad member to get updated by the squad staff member especially if there's upcoming activity or event soon or later. This is useful when they are going to have plan for their squad to entertain players to join the squad. I'm Positive good luck
The command should be /ssmotd. I am supporting your suggestion just because it will be useful for the active squads which always organizes events especially the squads that are actively participating any events and cool role playing activities of their squad. I would also include that this will be useful for the only staff announcement of meetings within the squad. Positive.
