Hi,

The default permission level for professors is 10. By default, only  
professors are allowed to administrate courses. This is controlled in  
the "Authorization system" section of the global.conf file. The example  
below if from the development version -- yours may look slightly  
different.

global.conf reads:

The %permissionLevels hash indicates the minimum permission level  
necessary to perform an action in the system. In this example, the  
"create_and_delete_courses" action requires at least the permission  
level $professor. The variable $professor has been assigned a value of  
10, above:

Hope this helps.
