It can be hard to communicate with a team.
(Especially if not everyone is all on a chat program like discord or Line).
Why not have a “Message of the day” ?
Perhaps make it visible to members only?
The alliance description has information for others out of the alliance to see, and I doubt anyone generally checks it on a daily basis, especially since it’s buried under a few clicks to get to. Most people pop on, do their stuff, and pop off.
