Hey Thanks for the info! I appreciate it.  I'll take a look at the links.    Are the hands on labs free to use forever?  I saw that I have "60 days" left.  Can I pay a fee to use them after that, or what happens after 60 days?  One of the things I was stoked about was how full-featured the hands on labs were, but would be unfortunate if they expire.  Thanks again for your help!
