Dear Patrick,
Fully concur with your comments.
News is only News when it’s new – but given Sophie’s rationale of members potentially missing items then your suggestion of a chronological piece makes absolute sense.
Perhaps it also the case that weekly is too often (and regularity and repetitiveness not fostering full engagement).
An alternative might be a monthly newsletter which could encourage membership to read more carefully with any important breaking news sent out as bulletins as and when required.
