Huh, I've read all the documentations but unfortunately I didn't find any clear answer yet. So, what exactly I'm looking for and what I've done? Let me say
-- I've registered a domain from outside WordPress.Com
-- Then I setup NS1.WORDPRESS.COM, NS2.WORDPRESS.COM, NS3.WORDPRESS.COM there.
-- Then I bought domain mapping from WordPress.com and point my domain to wordpress.com blog using $12. Suppose my domain is oyepagal.com to oyepagal.wordpress.com
-- It was working fine. Life was good and I was loving WordPress.com
but suddenly I feel that I need a sub-domain like store.oyepagal.com and I want to host this sub-domain to another host (Not on WordPress.com) like justhost.com with cPanel.
Then I bought my another hosting for my subdomain from JustHost.com to run my store on subdomain.
-- So, here is I'm stand alone. I've my blog on WordPress.com and I need a subdomain for my example store. and I've three options.
1 - Domain Registrar (Where I setup NS123.WORDPRESS.COM)
2 - WordPress.Com (Where I bought $12 domain mapping)
3 - JustHost.com (Where I want to host my example store for sub-domain)
Look what exactly my position is my main blog like carlatavares.com is on WordPress, and I need to setup store something like http://new.carlatavares.com
Tell me how can I achieve this? or from where I can find documentations for this issue?
PS: please don't send me to other documentations, I've spent 1 week to read all documentations. I need a clear answer right here.
