To setup, we make a PR on babel/notes and then setup a doodle for availability each week (and we make a Slack call or Google Hangouts for the chat). Currently, we usually do video chat on Mondays at 10:00 PM EST.
If we don't meet, I usually post a summary of what's been going on (notable issues/PRs, etc).
New notes are added as pull requests (watch the repo!): feel free to comment on them!
To know about our team members, please check out our team page!
Most of our discussions happen in the #development/#discussion slack rooms. (Sign up at slack.babeljs.io)
When we didn't have "meetings", but just notes to discuss development. These notes started July 30, 2016.
