I still have the Impress document, Simple_Presentation.odp. I made 2 years ago that shows how to create a a slide show. I thing it was uploaded on the ODFAuthors website at the time, but I don't remember where (OOo or LO). The license page lists this license: This slide presentation is Copyright © 2010 by its author, Daniel E. Lewis.

It probably would still be useful, but I don't know where it should be uploaded to. Earlier I saw something about where, but I probably deleted that email, not realizing that I might need it.
