[Sketching17] Sketching 2017 Slack

[Mike Kuniavsky]

In advance of Sketching I put together a Slack for discussions before, 
during and after Sketching.

The following invitation to sketching17.slack.com will work for a week or 
so. After that I can send individual invitations:

https://join.slack.com/sketching17/shared_invite/MjAzNjYyNDg3OTExLTE0OTgyNDYxNDktMTQwYjIyNzIzMA

Ping me if you have any trouble logging in.
