We could use a place to collaborate on migrating to and supporting GitLab. Discussed using WMF Slack, but that excludes most people who don't work for WMF. #wikimedia-gitlab it is.
Via @hashar, notes on process at https://meta.wikimedia.org/wiki/IRC/Instructions#New_channel_setup
Various bots (Phabricator, Gerrit if needed) can then be configured and our IRC operators on #wikimedia-ops have a few more bots to offer. See comments starting at T286770#7457672
