We primarly use email and IRC to communicate. Please note the code of conduct, which you’ll be expected to follow in our spaces.
We have a mailing list here, which has updates from the devs and occasional discussion.
We have an IRC channel on Freenode,
#robigalia, for more real-time communication. In practice, this is definitely where most communications takes place.
There’s a twitter account where new blog posts get posted. Feel free to tweet at us!
