Classroom Blogging Partnership via Ning.com (outside USA)

Hi.

I am teaching a course called learning.21st. I am looking to match up my Minnesota classroom with another classroom somewhere in the world. My students have been blogging on various topics and I am interested in working with someone on a combined assignment or two. It can even be as simple as having your students comment on our blogs.

We are doing various web 2.0 topics related to internet safety, collaborative documents, and other random topics. My students are 16 years old. My class uses Ning.

I'd like to see how collaboration works inside of Ning but I would be open to using outside applications.
