I am looking at it eight now, and still have no idea what to do. Do I own formulaoneupdate.com? I don´t think so, my blog name is formulaoneupdate.wordpress.com, does that mean I own it?
The second link tells me how to remove existing name servers(WTF). All of this: You can usually change your domain’s name servers at your registrar’s website, but the process is different for each domain registrar. Instructions for popular registrars are available here— if your registrar isn’t listed, visit their website or contact their support team for assistance.For certain domains, such as .com.br and other non-US domains (or ccTLDs), your registrar may require us to add a “Zone Record” on the WordPress.com servers before the name servers can be updated. Please contact supportand state the domain you want to map, and we’ll take care of this for you.
Domain Mapping for IDNs, also known as Internationalized Domain Names, is currently not supported on WordPress.com sites. (Your domain name is an IDN if it contains language-specific characters such as ä, û, ע, ж, 字, मा.)
is completely nonsense to someone like me.
