HI, I am brand new to WordPress. I had first made an account on wordpress.com come then found out that wordpress.org is the tool for me. Now I want to transfer the site I have made on wordpress.com to wordpress.org. Do I need to buy a domain and hosting first to transfer the wordpress.com site to wodpress.org? I apologize if this sounds a stupid questions but I am very new and still trying to figure out how this works.
