mastertheglobe on "Signed up my name only but how do I get a blog site now?"

Hello, Let me start out by saying I am very new to all this internet stuff. I want to start a blog. I found this site and signed up my name only as I have a domain name with GoDaddy. I think I may have done something wrong as now I can sign on here but see no area in which to start building my blog. Can someone please tell me what I may have done wrong?
Thank you in advance, Marc
