Second Life has an Info Island
Second Life, http://secondlife.com/ is a virtual 3D world entirely built and owned by its residents.
There is a new Info Island: http://infoisland.org/about/ (scroll down). There are opportunities to volunteer.
Today on the IA Institute list a member comments that non-profits are using Second Life to teach, host events, hold meetings, share technologies, and reach out to their particular audiences.
Are there possibilities for STC?
