So last year I upgraded one of my blogs by registering a domain name (becuzwecan.com) with wordpress and mapping it to my existing blog. Tomorrow it will expire, and I had wanted to renew my registration of the domain name with wordpress, but I don't want to have the domain map to my blog. I have created a new blog and I'd like the domain to redirect there.
So far I am confused about two issues.
1) Renewing the domain name registration with wordpress without also renewing the mapping to the existing blog.
2) Re-directing the domain name to a new site.
I figured this would be a simple matter of editing the DNS, but my host doesn't supply it in the format wordpress asks for, nor do I really understand what wordpress is asking for (the main one is what "MX #" means, and what number that's supposed to be).
Any help would be especially appreciated. Thanks!
The blog I need help with is becuzwecan.com.
