Thank you Nate!  That's exactly what I needed to know.  I know I need to set up with a WordPress capable host, but I'm not willing or able to set up and pay for a brand new hosting plan without knowing if I can make it work first, just to test out themes.  Since my current site is already with GoDaddy I want to just move everything over eventually without starting all over money-wise, and end up paying for 2 GD plans.  Will I have to pay for another year of GoDaddy?
