Debbie,
The chats are posted on the YLD email list Yahoo Groups site. Since they are weekly chats, and the transcripts are done by volunteers, it's easier that way - then the older ones are on the site where you were looking.

I assume you are signed up on the YLD email list?

Go to the web page for that list ( http://health.groups.yahoo.com/group/YLD ), then click on Files over on the left.

Then you will see a separate folder for each chat time. Once you click on the folder for Wednesday nights, you can scroll down the page and find the one you are interested in.

Hope that helps!!

Kitty
