Thanks for the info. I did find the link but when I try to use it I get a message saying it won't work until you are at Administrator level, and even then it just puts you back to enthusiast level, which is where I am. I will try emailing the address you posted. Suppose the easy thing at this point would be to create a throwaway account, redo the beginning level then delete the account. Might just go that route. However I will say it would make sense if there was a simple way to go back and review previous material.
