Discussion Groups

IRC Channel - English

irc.freenode.net #ocaml
This is a real-time communication channel, where you can ask for help. There are about a hundred users hanging around; don't ask if you can ask, just ask, and be patient: not everyone is in the same timezone. The IRC Channel can be accessed through a web interface or any regular IRC client.

Public channel logs are available at http://irclog.whitequark.org/ocaml/

If you wish to use a web-based IRC client, you can use Freenode's webchat https://webchat.freenode.net/. For a fancier/nicer interface, you may try https://vector.im/beta/#/room/#freenode_#ocaml:matrix.org -- it requires registration but is otherwise free.

IRC Channel - French

irc.freenode.net #ocaml-fr
As above, but for French speakers.
