how to assign custom domain name to blogs?

[lemon_1800]

for wordpress, you can do this easily by choosing Fantastico De Luxe on cpanel, then select wordpress to install wordpress blog to your domain.
For blogger, I don't know how.

Well, do we get control panel to manage our blog posts in wordpress.org website? Or else, are you talking about the fantastico installer which we find in our host server control panel?
