Is there a way to clear the tracker?

Is there a way to clear the tracker so that it no longer says there are new messages? I don't read every thread, so it would be nice to be able to clear the tracker to make it easier to find posts I haven't read.

Maybe clear the tracker when you log off, so that it only tells of the posts made since you were last logged into for the forum, or provide a button to clear the tracker, so you can easily see new posts when you refresh.

Thanks,

Don
