In the admin panel, look at your Widget for the slider and configure it. You'll see options to choose which "sections" appear in the slider. Any articles that have not been assigned to one of the sections you see in the list will not appear on the slider.

To create "sections" go to the admin panel and in vbulletinCMS, click on section manager. Think carefully - these are hierachical, so articles can only fit in one section, unlike "categories" which are 1+ for an article.

Then when you create an article, choose the "section" you want it to appear in from the list on the right hand side of the article creation page. Go back and modify the sections for your old articles.
