The E-learning platform used  at AUBG is .LRN™  - an Open Source solution, originated in MIT and ported to OpenACS (Open Architecture Community System). .LRN provides a complete portal framework along with out-of-the-box capability for course management, online communities, content management, and learning management. 

.LRN is a course management system designed to support traditional education, by extending the class in an on-line community.  .LRN gives students, professors, and teaching assistants a way to communicate with each other online. Students can find their daily calendar, which contains lectures, assignment deadlines, personal, and other events.

.LRN at AUBG can be reached on http://dotlrn.aubg.bg  (Registration with AUBG credentials is required).

The current .LRN Release Version is 2.4.1 and contains forum, file storage, calendar, news, survey, FAQ, homework dropbox, and group email as ".LRN-certified" applications. Weblogs, assessment, news aggregator, html editor, web powerpoint, complex survey, photo album, and learning objects are .LRN compatible and will be made available in future releases.
