Security Tips

I've posted all the useful blogger tutorials I can think of, so I was thinking about branching out and writing some tutorials about other computer/IT subjects.  I just got a new 1tb hard drive for my birthday and the first thing I did with it was encrypt it (which took 38 hours, but 1 tb is a lot of space).  This gave me the idea to write a tutorial on encryption and security.  So I'll put that up soon if there's any interest.  I would do it now, but I'm not done yet.
