How do we know which threads we've posted in

So, for example, I didn’t get notified when GreenWyvern posted to this thread.

Go to the bottom of the page and set the thread to Tracking rather than Watching. Then you’ll get a notification. See also Preferences > Notifications on your Profile page.

Thanks! Is there a way to set that up automatically? (BTW, since you quoted me, I did get notified)

Looking down there I see it is set to tracking for me with the following text: “You will see a count of new replies because you posted a reply to this topic.”

Looks like “Watching” might be closer to the concept of a subscribed thread, and it further looks like just the act of posting is able to auto-assign that thread.

Can we or should we switch the automatic assignment when you post from Tracking to Watching?

Unread is pretty much what you’re looking for
