We do ask that discussions on the mailing list be kept on-topic.

Gitter provides a persistent chatroom for nanomsg. You’ll need to use your GitHub account to join. Join the Gitter chat from your web browser here, or you can use Gitter’s nice app (which is available for all major platforms.)

There is also an IRC (Internet Relay Chat) room on #freenode for nanomsg. Unlike Gitter, IRC is not persistent, and does not require you to authenticate. Note that owing to its lack of persistency, the nanomsg core team prefers Gitter, so if you need to reach the developers please use Gitter instead.

Join the nanomsg IRC chat from your web browser here.

To access the chatroom from an IRC client connect to irc.freenode.net/8001, channel #nanomsg.
