J,
I want to sort members by their last posting date. Does anyone know
how to do this, or is there possibly some easy kluge?
I don't, alas, but that's an interesting idea.
I haven't been paying attention to the API interface, but maybe that's the sort of thing one could implement via the API, if one were a programmer with the relevant skills.
For us mortals I wonder if this could be made a filter (under the funnel icon) for the Messages (and Topics) lists: "latest message by member". Then with the filtered results sorted by date you'd have that list, including subject line links and snippets of those messages. Correspondingly, another filter could be "earliest message by member" - to answer the related question.
Combine that filter with the existing date range filter and you could get a list like "who posted in 2017".
The disadvantage I see with this proposal is that you don't get a convenient table view of them. But maybe an exportable table view of message lists is just a viewing option, a different feature we could ask for.
