User Group Navigation Tools

[eddie_vanhoosea]

I've created user groups in order for teachers to create conferences (BigBlueButton) with groups of students that are in different classes.  This creates a group for those students to access in the Global Navigation Bar.  When they enter that group, even when not a leader, they have the capability to create discussions and announcements, upload files, etc.  Fortunately, only the leader can create a conference. 

Is there a way to disable some of those tools or the ability for students/non-leaders to access them?
