In the "My Posts" rundown - why does it always say "Remove"?

Every topic I have -- it says "remove" on the first line. What does that mean?

If you click 'remove', it will remove that thread from your list. It's basically so if you don't care to see if anyone has added anything to the thread, it doesn't keep coming up to the top of the list.

You can click Remove if you're finished posting in a thread but when people post to it, it shows up again.

Why don't you click on it, and find out?

Thank you for making that clear.
