RWW CG slack channel

Hi All

For those of you not familiar with 'slack' it's a web based chat and
project management tool (imagine IRC on steroids) that can helpful for
productivity.

I've started an RWW instance at:

https://rww.slack.com/messages/general/

I think now that we are working with more RWW apps, it could be a useful
tool, for example, to test interop between different systems.

Please let me know if you'd like an invite.

Best
Melvin
