I just read an article about a website called http://www.slideshare.net- where you can upload and share powerpoint presentations. If you have ever uploaded them to the web, you know how BIG the files usually are! That's why people started using Camtasia ( plus they also can add audio...) Anyway, I thought you might enjoy a slide presentation on mobile communications that I found at http://www.slideshare.net/swamicrm/mobile-marketing/
Please let me know what you think!

Thanks,
Kathy
