If your school uses Google accounts, listen up. YouTube For Schools has just launched and it's an easy way for schools to manage YouTube access. It lets school administrators have a more granular way to oversee the type of content viewed in school. A typical way it'll be used is letting admins and teachers log in to watch any video while students are limited to only YouTube EDU videos.
Google released three official extensions: you can view your Google Calendar, clip web pages to Google Docs, and view your YouTube feed right from Chrome's navigation bar.
