You can get in touch with us via email, via Twitter (@wordcampbern), or via Facebook.
Additionally, we started the unofficial WordPress Switzerland Slack channel as a permanent place for anyone interested in WordPress to exchange ideas and tips. You can sign up for free at wpch.slack.com using your WordPress.org email address and say hi in English, German or French.
