Unfortunatelly, I can't do anything since I can't populate my front page groups with users. In the right pane of the display where potential users should be listed, I see an empty box whatever I type in the search box below.
Does anybody know if this functionality is currently available? I'm using the latest moodle 2.0 release . Also I would like to know what capabilities emerge from these site-wide groups in the current 2.0 release?
