Azul3D is currently composed of a small community, but we have large plans to expand!
Azul3D code base and issue trackers are hosted on GitHub.
The primary form of communication is a Google Group mailing list.
You can follow @GoAzul3D on twitter.
The Gopher Academy has a Slack group for Go programmers. Slack sadly does not provide open-access groups, but you can request access easily through a online form.
Once inside, search for the #azul3d channel.
The Azul3D Facebook page has news announcements, etc.
There is a FreeNode IRC channel #azul3d (note: less used than Slack).
The /r/azul3d subreddit often contains news submissions.
