ProjectForum can create slideshow presentations from your pages.
A slideshow consists of a number of different slides, all put in the same forum page. Slides are divided by horizontal rules. Everything up to the first rule is discarded, which allows you to include other notes that will not be included in the slideshow.
You should use headings to provide a title for each slide. Other than that, you can use any other formatting for each slide, images, etc. Of course, bullet lists are quite common.
Include the tag [slideshow:] in the page, which will produce a button that will activate the slideshow.
