I don't know if this will help or not Gooddeeds but I was initially unsure of the benefit of having watched threads and unwatched threads and all that jazz... until I used the "mark forums read" button. That is when the system started working for me.
It marks all of your subscribed (watched) threads as completely read at that point and clears them from your watched threads tab, but you can still find them in your history tab if you want to refresh yourself as to what was last going on in the case. Anytime someone makes a new post in one of your watched threads the thread shows up again in your watched threads tab where you can go to see the new replies. Clicking on the little blue dot at the left of the thread title then takes you to the first unread post.
Tortoise, thank you. Where do I find Mark Forums Read button? I don’t see it.
