Thanks for the replies!
I have the option in the preferences of When I don’t visit here, send an email digest of what’s new: enabled and set to Weekly, but have yet to receive a email message from the forum.
Do I perhaps need to enable something else for those recaps?
I do see ‘Unread’, but that currently stands at 1 topic for me. If I hover over ‘Unread’, I see that is only shows the topic I’m currently watching or tracking.
That means ‘Unread’ contains unread posts from topic already known to me.
I do see ‘New’, and that currently stands at 70 topics. The text of that link says ‘topics created in the last few days’. So that will be the new topics for me.
What’s missing in my view are the unread posts in topics that I do not watch or track.
Perhaps the Automatically track topics I enter setting can help, which I’ve now set to ‘Immediate’. If I understand that setting correctly, now I’ll track everything I read from the ‘New’ page so that, on my next visit, it appears in the ‘Unread’ tab.
