System froze twice on my above average MAC and DSL. Will need to explore the issue and try again. This was also at the end of a very long day for me with the session at 10 PM EST that started at 6 AM EST. SO it was easy to bail. I'm a Second Life newbie and frankly disoriented there. However, I haven't spent much time there.
For those interested in giving it a whirl, ASTD in SL allows you to put a toe into the Second Life ocean. Anders Gronsted hosts SL sessions on Tuesdays at noon EST. Anders has written several T&D articles and it a veteran presenter at ASTD Conferences.
