Just one update for you this week, but it's quite large.
I've added a Second Life mini site to the 3D Worlds & Websites page.
The mini site has it's own URL so you can go to it directly if you wish: http://sites.google.com/site/secondlifeenhancedlearning/
On this sub site you will find my favourite links to free resources both in Second Life and on normal web sites that allow you to provide your students with enhanced learning opportunities within Second Life.
Anyway, feel free to take a look - feedback is welcome!
I hope this is helpful to you.
