If I buy my own domain eg: http://www.xyz.com and transfer my current blog eg: aaa.wordpress.com who will host the blog. Do I have to buy wordpress credits for hosting or look for a hosting provider of my own choice and run my own WP installation.
well I just recently did this…and I’m a computer dunce so someone can correct me if i’m wrong..
the place you ‘bought’ http://www.xyz.com is the domain registrant but wordpress is the domain hoster. you need to configure the something or other (dns maybe it’s called..I forget) on http://www.xyz.com so it points to wordpress (there are instructions for this in wordpress faq). it’s 10 credits to domain map, if I recall. after you purchase the credits, go to your dashboard and I think it’s options-add domain. very easy after that. :)
Changing domains? Probably as you would be basically starting over from stratch until folks found you again.
What you could do is go ahead and get the domain mapping here with the xyz.com domain, sit on it for a couple of weeks until folks get used to teh new domain name and adjust their links, and then move by changing the name servers for teh domain.
