As a means of supporting professional development and collaboration in our district, we have recently opened some additional features of Google to our district staff and students. Among those available to Staff is "Google Hangout," a video chat service from Google that enables both one-on-one chats and group chats with up to ten people at a time. If you're interested in "Hanging Out" check out the links below to help you get started.
