I’m sure it does, but having them by way of reminder on a board has its uses. I have a way of tracking participation in my rules that I feel is fair and rewards effort and gives people lots of chance to redeem themselves if they go through an unproductive spell. So it has a number of steps / checkpoints. I find it easy enough to use to track, but it’s lengthy to explain in in-game chat (it’s here). As a result the introductory explanation to a new member would only really be a summary of the policy, so it would be handy to have the full / detailed outline (and perhaps rationale behind it) in an accessible form in-game.
This is not mutually exclusive to the introductory chat, which is always a nice welcome for a new member in any event.
