Tioki is a professional network for educators that reminds me of a cross between a Ning network and Linkedin. This is a great place for educators to create a profile, display their skills, and find/collaborate w/ other educators. What makes Tioki nice are the innovative features such as: interactive whiteboard, the ability to demo a lesson, or the ability to create a event.
I highly recommend checking out Tioki by clicking here!!
