Ning is a social networking site that can easily be used for the classroom. It can be set as a public site or a private site to provide more safety for your students. There are multiple options to make the site the best it can be for your specific class. Groups can be created, which may be helpful for group project work, and the groups' progress can be observed more closely by you. Events and due dates can be listed in another box. You can also list notes for the class in another area. The blog is another interesting option. Not only can you have class discussions through the blog, but you can also have some of your posts done in advance and just list the date you want the site to post it, so it is not forgotten.
The chat option can also have different uses. You might have an hour every night in which the students can ask you questions. The site can also be used to easily send class wide email.
Bing also has music, video, and picture options. You can use these options to post podcasts or videos you want your class to see. You can also take pictures of your class activities and post them on your bing site.
