We've just launched the Errai community site: http://www.jboss.org/errai
We are launching this community site early in the process to spark interest and engage the open source community.
For one, because we believe in what were doing, and we feel that the project is now at a point where it's time to branch out and join the greater OSS community and let our hard work finally see the light of day.
So, on behalf of the Errai Team, welcome!
