Skype has caught on to the idea that they are a valuable educational tool. Now there is Skype Education which is slated to launch in December. The idea is Skype wants to create a directory for teachers and classrooms to contact each other. So when Skype Education becomes available it will be a great way for teachers to connect with one another using their directory.
When you visit the site you can provide some information to preregister to add your name to the directory. I suggest the first place Skype looks is the directories that several educators have taken the initiative to start themselves and add those to the directory. You can find those directories on a previous Skye Resources blog post that I did.
