Slack

For those who like the Slack environment for communication, there is https://osgeo.slack.com workspace.

You can sign in to the OSGeo workspace using this invite link: https://osgeo.slack.com/messages/C07RKJ06B/

In case of problems with signing in, you may contact User:Mloskot or User:Jive.

OSGeo maintains a presence on slack due community demand, the main communication channels are available via IRC or Matrix environments (which are, contrary to Slack, Open Source based.)
