May I ask why you feel aggrieved that members did not respond to your posting in great numbers? You have posted some information that may or may not be of use to others. You have contributed. That is all we ask of you. You do not need universal acclaim to validate your actions.
Content Presentation
This item has been around for many, many years. Rather than present it in a time-consuming, fancy PowerPoint presentation, I think it would have more impact being presented solely as an easy-to-read list, as it has been in the past. Content is far more important than fancy, whiz-bang presentations, but maybe that's just the trainer in me!
