Microsoft Learning Gateway [Wikipedia]
Microsoft Learning Gateway (MLG) is a Web-based collaboration, communications, and content delivery framework that serves the education industry.
The MLG helps in creating integrated e-learning solutions for primary and secondary schools and higher education institutions.
Developed to deliver education-specific functionalities, an MLG-based e-learning solution means that every associated teacher, student, and family can be connected from their home or school to the Internet through a proxy or firewall server, or through a hosted service. With Microsoft Exchange Server, each user can have a secure e-mail address.
Using a Web-based service enables students to participate in lessons and complete assignments online through the portal, both from home and at school.
