Webmaster tools is very useful if you want to know what is going on with your sites and Google. In order to use the tools you have to verify ownership of your site with one of their given methods. This was not possible with ENV1, but it is now possible with ENV2, or the Blog Beast, at the condition you use a valid domain name you own.
Using the sub-domain gmichel.empowernetwork.com for example will not work as there is no way you can verify with a domain you do not own, no possibility of inserting code in your posts, or access the server via FTP. When you have a domain attached to your Blog Beast, like this one www.MichelGerardOnline.com, you can verify with Google Webmaster tools.
In my other blog I wrote a detailed tutorial on how to do this: CLICK HERE
