Don't you have a line of links across the top of the page like this: Popular, My Friends, My Topics, My Posts, My Tags, New Topics, New Posts?
If so, how did the threads listed in your My Tags list get there? Mine got to my list by me tagging threads I read regularly. But since it has been many years now since I tagged them, I've forgotten how I did it.
I asked the question in the Ask a Question Quick Link at the bottom of the page but didn't find the answer.
Somebody must know how to do it.
