I can find this thread because I have a post in it (or I can do a search). But it does not seem to live inside a category. It just seems to be hidden from a person just browsing the forum.
Where is this thread and how would a person who had never posted to it find it? Maybe (let me change that to ‘most likely’) I am missing something obvious. OTOH, given the intended nature of this thread it seems surprisingly inactive.
