If you're interested in moving some of your librarian educational services online a bit more I recommend you take a look at Wiziq's virtual classroom and authorstream's power point presentation platform. Both are web based, have a bunch of features and free basic service.
thanks for the reply. I'm only a casual teacher, so teach all around the place, mainly south western sydney (liverpool, lurnea, etc)
Really nice to meet you. hope to share some ideas with you.
