My role in the discussion forums is that of a "silent facilitator". I provide daily private feedback - corrective and supportive - to the student discussants.
Thank you - a funny thing happened with this. I was working with Bill on something and mentioned I use this in my training. He said he had no copy of it and asked me to forward. I had scraped it off the old SLN site and made a pdf of it for my faculty to use offline. So it is good to see there is a new source for this I can link to in my training. They do love this!
