Birzeit University/Palestine has been using a modified system based on ACS4 since April 2002.
The System provides much functionality for students, instructors and administrative employees, starting from the simple student schedule to a complex online registration process.
Birzeit now is in the process of adopting .LRN (we'll be running v2 as a system for Training Courses before the end of the year.)
We plan to extend the system to do some financial and human resource management for the courses... I'll be posting our progress...
