Actually it's a pity that we don't have a common chat/mailing list. We have this Google group, there is a Slack (mostly by @mrkn): sciruby.slack.com, there is a Gitter channel (by @kou): https://gitter.im/red-data-tools, and we have/had the Freenode channel #sciruby. We should be together, not on different channels Best, Andrei
