To help teachers around the world connect their classrooms, Skype is developing Skype in the Classroom. Skype in the Classroom, launching in December, will be a free directory of classrooms that are on Skype and are looking to connect with other classrooms. Registration is open now for those teachers who would like to be in the Skype in the Classroom directory.
