I've logged in at SalesForce.com and then clicked "Run Tutorials" (enrolled as basic developer). This takes me to DeveloperForce with a list of tutorials.  Where does one go from here?? Nothing clicks or activates and it appears I've been signed out (some button called "De Login" appears at the top - signing in again just repeats the loop).

Also dl'd something called Force.com Workbook and see that I have to create something called a Sandbox. However, nothing resembling "sandbox" appears on the path yourname>setup>data management>sandbox.

Any assistance would be greatly appreciated.
