Moodle is a very intuitive piece of learning management software. The material for each course is broken down into weekly bits with various activities to do each week. Please feel free to experiment with the system as you can't hurt anything here -- if you run into problems please send email to:

postmaster@rboblee.com

and you will receive a timely response to your question. You might wish to experiment with Moodle by attending the "Experiment Class" which is found in the courselist under the "Miscellaneous" section of courses. The "Experiment Class" only shows a tiny piece of Moodle's abilities -- Moodle can do everything WebCT or Blackboard does and more, and does it better.
