 ### K9s Slackers
 
 I've enabled a [K9s slack channel](https://join.slack.com/t/k9sers/shared_invite/enQtOTAzNTczMDYwNjc5LWJlZjRkNzE2MzgzYWM0MzRiYjZhYTE3NDc1YjNhYmM2NTk2MjUxMWNkZGMzNjJiYzEyZmJiODBmZDYzOGQ5NWM) dedicated to all K9ers. This would be a place for us to meet and discuss ideas and use cases. I'll be honest here I am not a big slack afficionado as I don't do very well with interrupt drive workflows. But I think it would be a great resource for us all.
