Thank you for the reply, it makes a lot of sense. The only issue I’m having is I can’t get Subject to display in the DisplayListItem web part. Discussion Subject displays correctly for the replies but not for the initial discussion entry (which I guess is expected even though I don’t like it!). Subject does not display at all.
In the DisplayListItem web part, for Primary Content/Display Fields, I’ve selected Discussion Subject and Subject for Content Type Discussion. I’ve selected Discussion Subject only for Content Type Message; Subject is not available.
Please advise. And thanks again for the suggestion.
