What tool did you use for...
For the ebook, I created the cartoon in Powtoon. I created the ebook cover using an online application that I no longer remember the name of and that you could probably find by searching "ebook cover." The ebook itself is a PDF file that I created using Pages on a Mac. There is no template for it.
For live online sessions, we use WebEx. Some courses also include links to examples that may be video, Flash, HTML5, or in other formats.
