Huge thanks to 42wim who’s created an IRC bridge for Mattermost using webhooks.
See the project on GitHub at matterbridge. Now listed in the community integrations section on the webhooks page.
Extra special thanks to 42wim for setting up #matterbridge on irc.freenode.net so community members can use IRC clients to talk directly the Mattermost core team.
IRC messages on #matterbridge connect with a new IRC channel in the core team’s Mattermost instance (screenshot above).
