Good day.
From your Profile page you must jump to "Subscriptions" to find post titles and links:

That is what Apple is calling our forum activity and seems to confuse many. Once in Subscriptions, the list defaults to the "Following" filter. Change the filter to "Participated" or "Authored" to get a more complete view.

👉🏻 Important note: Although any posts you make remain on the servers in perpetuity, the Subscription page only goes back about three months. To find your posts older than that, you must a search engine and, for you, this search string:
site:discussions.apple.com "adolfgarlic"
Save that someplace and paste it into a search engine's address window when you need it. Note there is NO space between the colon after "site" and the "d" in "discussions.
