I have sent you part of the text for the presentation - and here is the Shockwave file fyi.  It takes a little minute to load, so give it some time.  The file is set up so that you can click right through it - every time there is a blinking cursor - and then there are some "next" buttons.  I hope these will give you a start - and more right around the corner.

Click on the link to start the shockwave file.

Always, Margie
