I thought I would post this one up
To track a post that you are interested in, while viewing it, you can go right
down to the bottom of the page, and click on "Bookmark topic" -- this link is
sort of on the left hand corner.
Now go up, and click on "User Control Panel" link, also on the left hand corner,
the first page selected is "Overview", click on "Manage bookmarks", you can see
all the posts you are interested in in there.
When you are no longer interested in them, you can remove them from your list,
by check the box, and click on the button that says "Remove marked bookmarks".
This way, we will not lose the topics that we are interested in.
Best regards.
