make sure you click through the “Latest” tab manually, or you will miss posts.
i just found two posts which i hadn’t seen yet, even though i was not notified about this. the unread topics seemed to have a slightly different shade of blue on the “Latest” tab, but this wasn’t very clear either.
i still trust the ‘Latest’ tab to be anti-chronological, but from now on i will just click every post on there once a week, just in case there were some new comments of which i wasn’t notified. you should too!
maybe notifications are only for threads in which you are already participating?
