A peak concurrency of 65,285 online residents in SL at 2:50PM SLT that is a new record. Remembers when I joined TSL there were only at the most 13,000 online residents back then haha.
At the moment there is 12,869,530 signups who have signed up to Second Life in which most are inactive however many are active today. If rates carry on like this we can except the 13th million user sign up in the next week or so.
