Gitano has an IRC channel on Freenode.

Webchat is available as provided by Freenode.

Gitano's developers are based in Europe, but usually get messages from other hours.

If contact is required out of hours then IRC isn't the best support channel, especially by the web chat which won't get responses while not connected.

Mailing list

Gitano has a mailing list for development and support. See the list info page for how to subscribe.
