Sink or Swim?

I'm dog-paddling for my life. This class is what I call an information explosion. I know this is the wave of the future and to survive, I must become skilled at this. (Read the waves).Who would have thought ten years ago we'd have the world - literally at our fingertips. Tuesday night's class was so interesting. I have tried to download what I need for the Stellarium website, but it didn't work. Any suggestions? My dad is an avid star-gazer and I know he'd love this site.
