Okay ... I'm assuming that you mean the little black dot on the bell symbol to the left of each thread title in the "View Posts Since Last Visit | View Your Posts" listing. Is this correct?
If so, then you may notice that many of those bell symbols do not have a little black dot. This means that you have not posted in those threads. The presence of little black dots means that you have.
Clearer?
