My rough imperfect translation is
- mute - I don’t care, don’t bother me
- normal - I’ll find them on my own thanks
- tracking - if it involves me let me know about it
- watching - I want to know about everything that happens
I have quite a few categories set to Watching and necro’d topics I have not previously visited in those categories come to my attention without a problem.
Any reasons Watching doesn’t work for you?
EDIT
(feels off-topic, but might be related)
Maybe not so much “without a problem”. It took me a bit of scrolling but I found a topic in the Feature category (that I Watch) that I had not visited, but was not a New and had the notifications level Nomal.
I’m guessing it was started in a category I’m not watching, was moved, and the edit history indicating the move was deleted?
