Free-math Google Group

I have recently signed up to follow the free-math Google Group.
This group has been set up by Aaron Leventhal, an accessibility expert of IBM - although there are rumors that IBM is letting him go - who also has an interesting blog, called Access Garage.

The free-math Google Group is joined by a bunch of experts of access to math, who discuss about that, propose collaborations, and analyze the current situation in math accessibility.

I think it's worth joining this group. Among other members, there are Dominique Archambault (@Science partner of Pierre et Marie Curie Université, Paris), and Neil Soiffer (Design Science Inc. engineer who collaborates with the @Science Network).
