Discuss issues to consider before sending presentation materials to the audience ahead of time.

 Consider sending preview study materials ahead of time. Doing so allows audience members to familiarize themselves with any important background information. By using a free service such as SlideShare, you can distribute your presentation slides to either public or private audiences, and you can record audio narrative to make your presentations function on their own. Some presenters advise against giving out your slides ahead of time, however, because doing so gives away the ending of your presentation. If time allows, you can prepare preview materials that don't include your entire slide set.

Such a godsend, you helped me and my friend big time
