Living Room / Re: Thinking about setting up a dedicated "secure PC" in my house.. Thoughts?

When the IT Dept gets rid of computers they either trash the hard drive and throw them away or give them to a recycling computer company to hipe the HD and resell them.  You should look into it.

I have found some amazing deals with off-lease computers.  Ubuntu, Linux Mint or another easy *nix might be suitable for you for these purposes.

Thanks for the idea on using #define for constants... I should have known better.

I'll post the updates soon.  Never know when you need to know how much your butt weighs on the Moon!  or Uranus...

HELLO.

This is due in my CIS C Programming class soon.  I thought it would be no sweat, but I ran into some trouble at the end because I cannot break out of a switch when the switch/case is inside of a while loop.  If you have any code suggestions please let me know.  I probably went about it wrong.  Maybe I should have used a flowchart or something. 

ok.  whatever.. have a look.  thanks.
