A recent question on what online educational tools people use generated a lot of answers, among them a suggestion to use Second Life.
I looked into it a few years ago and it appeared to me that Second Life is not really alive anymore. Particularly, there seems to have been an issue whether to change from an installable application to a browser-based application.
I design eLearning modules in the field of accounting and business, including statistics, and I was wondering whether there is any experience out there you would like to share.
