Google Webmaster Tools Says "You Have More Sites" To Add

If you login to your Google Webmaster Tools account, you may be prompted to add more sites to your account.

When I logged in this morning, I saw:

You have more sites!

You're also a verified owner of these sites. Would you like to add them to your Webmaster Tools account?

This was followed by a list of domains and then two buttons:

• Add selected sites
• Always add

Here is a picture:

I should note that many of these were the non-www equivalent of sites I have already added to my Google Webmaster Tools sites list. It is best practice to add both the www and non www.
