Hi, this should be a common request to the WordPress staff by now:
I have the same issue as this guy --> http://en.forums.wordpress.com/topic/register-blog-dns-to-a-zone-combr?replies=2
So I believe what I need is a "DNS zone record" for "www.pitukinho.com.br".
Thanks in advance!
The blog I need help with is pitukinho.wordpress.com.
