Dear Hub servers forum subscribers,
As the Hub servers forum has become rather quiet, with only two posts in 2017, we're going to move the discussion threads to the General help forum and then delete the forum.
If you still wish to receive notifications of Hub servers discussions, you are welcome to subscribe to individual discussions.
Please note also that in Moodle 3.4, support for additional hubs has been removed from standard Moodle (MDL-59495), though plugins for custom hub registrations are available.
