Domain name information doesn't actually "propagate", but yours should have been updated on the DNS servers by now. Your Name Servers appear to be set up correctly.
Domain Name: MERRICKMOTHERS.COM
Name Server: NS9.BRAVEHOST.COM
Name Server: NS10.BRAVEHOST.COM
Are those the server names that Bravenet provided, when you registered the domain name?
However, when I try to use your URL, I get a DNS error
DNS Error (dns_server_failure)
This usually means that your problems are with Bravenet, and you will need to open a trouble ticket to get it resolved.
Did you also register for hosting at the same time you purchased the domain name? Sometimes users purchase a domain name, without registering hosting at the same time. You can use the free or paid hosting with the domain name, but Bravenet needs to know where to point their DNS.
