The CNCF has a Slack workspace available for all community members and registrants for KubeCon + CloudNativeCon North America. 

There are a few main Kubernetes channels, most of which are focused on KubeCon. You can find announcements about the event, a help desk, a channel for talking to other members of the community, and a channel where sponsors can post their plans and giveaways.
