Since both the Slack and IRC channel aren’t extremely active I would propose to mirror both channels using something like slack-irc. I have a small DO server running where I could run the bot needed for the mirroring.
Thanks for the offer The Atom team is happy with Slack for now.
Am I missing something? The #atom channel over at freenode is official right?
It does state so in the channel topic: “Official channel for the Atom editor”
