Hello all, I hope I'm in the right place or can be directed to it.
I am doing some research into the use of Second Life as an educational tool, and in my research I'd like to back up some of my results with statistics from the usage of Second Life over the years. I'm particularly interested in either the number of (distinct, if possible) log-ins or the total number of hours spent in Second Life. I've found things like http://dwellonit.taterunino.net/sl-statistical-charts/ which is very interesting but doesn't cover a long enough time period or present quite the data I'm after.
So in short, is there somewhere these statistics are published or someone I should speak to for them?
Side note: a few forum posts and even papers I've read have stated that Second Life is or has been in use at hundreds of universities. Is there any way to track its uptake in higher education institutions, to put some weight to these figures?
