Quoting Jai mail@jaipandya.com:
Bill, Thanks for the link to drupal-education group. Now, I am also a member of it. I found it very informative and some of the group posts instantly solved my confusions. Also, here I am more concerned about a public facing website using drupal with the facilities I listed in my first mail. For the collaborative/learning environment I find moodle to be a good out-of-the-box solution. I was searching for the ways so that moodle and drupal could be integrated in some way.
Jai, I don't have the reference link in front of me that Bill gave you but wanted to point you to http://elearning.psu.edu/drupalineducation/moodle as a good reference.
