If you’re coming back to the community after a few days off and want to see what you’ve missed, there’s a handy tab to help you get caught up. By default the community goes to the Latest tab, but a couple tabs over you’ll see the Unread tab:
It will have a number in parentheses showing you how many topics you have to catch up on. One you go to that tab you’ll see all the topics with new posts since you last visited them. There will be an indicator of how many new posts are in each topic:
Clicking on the topic will take you to the first unread post in that topic, so you don’t have to scroll down to find where you left off.
To the left of the Unread tab is the New tab which shows you new topics since your last visit that you haven’t visited yet.
