And to clarify what I was saying, I already edited my first reply (my edit is in parentheses) to add that the reason using the subdomain might be no good is it could be a security risk. If DW redirects support.dreamwidth.org/ to dreamwidth.org/support, then so can anyone else. You just do not want this; I've seen too many examples of Blogspots being redirected to websites without the Blogspot owner's permission to ever want to see this suggestion implemented. All it takes is a simple change in the DNS/MIX records to pretty much do whatever the heck you want with a subdomain that is set up to allow such redirects. Your suggestion scares me, put bluntly (I was trying to avoid having this conversation, but since you sort of asked).
