It has been active for a while now but somewhat quiet. Also, it was by manual invite only so that was a bit boring. Now you can self-invite thanks to the excellent [slackin][1] project.
Slackin hosted on a free azure web app - https://cw-talk.azurewebsites.net/ (It may take a while to warm up if no one has visited in a while so be patient please!)
I had to move Azure accounts and setting up Slackin was a massive drama. Since slack is not exactly active I have decided to return to manual invite only mode and save on the node/npm/gulp/grunt/git/bash/avocado hipster tax
