Topics being watched disappearing

My question is about this one here. What to do to stop making the threads marked as being watched disappear? I can´t remember what they were called so I can´t use the search and there´s no point in opening threads/posting if I can´t read the answers later on so.

Profile>preferences
Always notify me of replies : NO
save

See if that helps.

No, I want to stop them from disappearing so I can go back to them and see the answers. If they disappear I forget where I´ve posted. The Show Your Posts doesn´t really save the posts either. Everything disappears.

Profile>Topic being watched tab

The topics are there !

Thanks.
But that was my point. For some reason they don´t stay there. Oh well.

Means, after clicking on watch this topic for replies. The threads are not displayed there?

Yes that´s right. I think they stay there as long as I´m on the forum, but when I leave and come back, they´re gone.

I did the advanced search and put my username in, but there are threads I´d like to watch but don´t want to post in or haven´t posted in.
