Talk league-wide or walk into a matchup room. Posts carry the franchise identity of the authenticated owner. Keep league business in the Rulebook/League Office; this room is for the people.
S.L.L. Locker Room is a league social space, not an official rules or transaction record. Commissioner moderation can hide or remove posts. Owner access reuses the private S.L.L. access code created for Pick’em; no second password system is required.
