This is one thing I am trying to figure out, too. If you go to the Unread page, it will show you the threads you are tracking that have new, unread posts, but it doesn’t list all the threads you are tracking.
On the old forum, the subscription page functioned similarly. However, at the old CAF you could click the “Show all subscribed threads” and it would then list all the threads you are subscribed to, even those with no new posts.
You can go to your profile and click the activity tab and it will show all your posts. But it’s not quite the same because it shows every single post rather than just the threads, and it doesn’t show the threads you may be tracking without posting in.
This is probably the one thing from the old forum that I most want to replicate here. I don’t see how to do it yet.
