Thanks again, Alan.

I am thinking that what I probably need is to 301 redirect all URLs of the form http://blog.<domain>.com/page</domain> to http://www.<domain>.com/page</domain>, yes? In short I don't want to use the blog subdomain anywhere so, to avoid SEO inefficiencies, I should presumably redirect as above so that everything ends up at the www subdomain.

I think

Thanks.

Mark
