Been my recent pleasure to welcome Paul Andrews back to Second Life. Paul was the third member of the SLOODLE founding tri-umverate, but left the project (and Second Life) for a number of reasons. Now, with a new job, he’s back. In his time away he’s continued to look at 3D worlds for e-learning – and has a nice section on these on his e-learning resources site.
Good set of materials on using Google’s Lively – including how to give a presentation in Lively (which currently does not allow you to upload your own graphics).
