Working?

That link suggests a change in the .htaccess file in our Root Folder.

However you are suggesting I have to change something on Google Webmaster.

Is it one, the other, or both?

Regardless do I need to make a change to other webmaster tools also?

The final question is how many total locations do we have to make this change to?

We have a main site

A greymatter blog system

A forum

We are on multiple webmaster tool things, like Yahoo and Google.

Please clarify before we change a bunch of things.

It would require a separate .htaccess for each site, as well as selecting the www. or non www. option for each site in the Google Webmaster Tools settings.
