I don't see a distinction between topics that are new or have had new replies added since my last visit. On the old forum, new/updated topic titles were in boldface. Is there some indicator for new activity I'm missing?
There is a red bar that appears on the left hand side of a post that lets you know you haven't read it yet. If you'd like to see a different mechanism in the community (say a whole widget of new posts or replies on the main page or a list at the top of the page), feel free to make a suggestion in the Ideas area.
Hope that helps!
The way that I usually see it is from the main community page>click on Unanswered posts (the title above the list) and then I get a list of posts I haven't read or that haven't been replied to yet.
If you're not seeing the red bar, let me know. It's likely we might need to change the permission or log an issue with our vendor, Lithium, regarding the difference. Thanks.
