@Stella, no offence, I don’t want to bother but you maybe should revise “North V South” section of your index. Click on your link and see to which posts the link leads. You’ve linked some topics to the specific posts but at least one is of no particular use and I believe it wasn’t the one you wanted to link to. If you would like to link the whole thread you have to go up top the topic and link the first post of it and if you want to link just a specific post you’d link the one which is useful. the links to the specific topics are those beneath the posts and not those at the top.
The example is What to learn North or South where you’ve linked to @pollypolly’s answer (just like I did in provided link) but I presume you actually wanted to link the post above or maybe the whole thread. One could scroll up and read, I agree, but still.
If I’m wrong in what you really wanted, just ignore this message or let me know.
