One of the interesting aspects of completing this project was the fact that many of the sites said their site was free and included most of the features on the chart. But, once you went to the site and signed up for free, not all of the feactures were available unless you up-graded for the paid site. The free site had just the bare basics to put together a presentation. Overall, all of the sites were interesting to play around with and if I had more time, I might have figured out if the features were readily available for free.
