 Maintainers have a variety of ways to communicate with each other:
 
 - Homebrew's public repositories on GitHub
-- Homebrew's group communications between more than two maintainers on private channels (e.g. GitHub/Slack/Discourse)
-- Homebrew's direct 1:1 messages between two maintainers on private channels (e.g. iMessage/Slack/Discourse/IRC/carrier pigeon)
+- Homebrew's group communications between more than two maintainers on private channels (e.g. GitHub/Slack)
+- Homebrew's direct 1:1 messages between two maintainers on private channels (e.g. iMessage/Slack/carrier pigeon)
 
 All communication should ideally occur in public on GitHub. Where this is not possible or appropriate (e.g. a security disclosure, interpersonal issue between two maintainers, urgent breakage that needs to be resolved) this can move to maintainers' private group communication and, if necessary, 1:1 communication. Technical decisions should not happen in 1:1 communications but if they do (or did in the past) they must end up back as something linkable on GitHub. For example, if a technical decision was made a year ago on Slack and another maintainer/contributor/user asks about it on GitHub, that's a good chance to explain it to them and have something that can be linked to in the future.
