I have installed Sakai on a dedicated server, and was looking into some features as deploying lesson builder. Does anyone know as of how to deploy this tool? Or any other tool like Calendar. I a newbie in sakai environment, so not sure how to proceed with such things.
Lessons is now included by default in Sakai 2.9.
Alternatively, you need to run the compatible tag for it to work in 2.8, check the install guide in the source for Lessons.
