Collaboration on Voicethread

Hi everyone,
I teach grade 6 science and math in Canada. My students in grade 6 have just completed animal adaptation projects on voicethread. The URL for the projects is http://voicethread.com/#u5853. My students are really excited to have comments added to their work, especially those with no comments yet. It would be great if you and your classes would have a look at some and leave a note for the students, please let me know if my classes can do the same for any of their projects. Thanks.
