Mandarin Learning Resources

I have been experimenting with the service at Twine. Twine allows you to store and share knowledge and still has a lot of rough edges (it is in private beta), however I think it has a lot of potential. I have started a Learning-Mandarin twine which I intend to keep populating with learning resources, also as commenting is allowed resources can be reviewed and discussed.

If anybody wishes to join Twine I have some invites.
