Welcome to WebmasterWorld Guest from 18.104.22.168
I'm going to go out on a limb and say you really don't need to do anything about it.
Put the redirect in your own individual htaccess and there will be no question about it.
but it needs to be done.
Dose not matter which one you redirect to www or no www...

If you set your preferred domain as http://example.com, we'll treat links to http://www.example.com exactly the same as links to your preferred domain.

[edit reason] fixed link [/edit]
Who in their right mind would want "www." in their address, when they don't need it?
