Can I share a presentation with Oomfo charts in them to my friend?

Yes. Oomfo has Export capabilities that allow you to convert all Oomfo objects to standard SWF objects that can be viewed by everyone. Before sending a presentation to your friend, click the "Export Charts" button in the Oomfo menu/ribbon. This will generate another folder containing all the chart SWF files in the same location as your PPT file. Send both the PPT and the folder to your friend, and he will see the charts exactly the way you made them.
