What are you trying to do? the best way for you to learn is to go a hosting provider, get yourself a domain (maybe your name) and get a Wordpress hosting service as well. Set that up (GoDaddy and UnthinkHosting.com) do it for you on their end. Then just play with the themes wordpress provides for you when you first set it up. try to design a good layout, install and modify plugins...etc. get yourself in there and just play with things. It can't be broken and if they do you are only a call away from tech support so they can reset.
