Disambiguation of this Slack from the Slackware Linux distribution's "Slack".
 Slack for discussions/chat
Slack is accessible on the web, as well as via IRC or XMPP clients.
 How to get on
Unlike Noisebridge's IRC channel, Slack requires an invitation to join. It's recommended that you meet up with someone knowledgeable in the space and talk to them about Slack, or if all else fails, request an invitation on Noisebridge-discuss.
 Why slack? - replacement?
Some are not comfortable with slack as it is (add!):
- corporate entity
- not free
- free open software
- stored messages
- realtime chat
- irc (not used, missing archive feature)
