Privacy policy change

This week I'm finally working on the social aspect of the Carbon Diet site. Testers will see a new "public" option on their settings page, and a "search" link which will let them search for public profiles. However, because I've now got down to the practicalities of implementing and using this system, I need to make a small change to the privacy policy. The old "public profiles" section said:

If you make your profile 'public', your emissions data will be visible to anyone who visits the site, but we will not make any personally-identifiable information (name, email address, etc.) visible to any other user of the site unless you explicitly allow us to (mainly in the case of adding 'friends' on the site who can see your personal data).

The new one now says:

If you make your profile 'public', your 'display name', country, and emissions data will be visible to anyone who visits the site. However, we will not make any contact information (email address, website, etc.) visible to any other user of the site unless you explicitly tell us to (mainly in the case of adding 'friends' on the site who can see your personal data).

I need to make the display name and country public simply because at least a bit of information is needed in order to be able to find someone's profile. However, you set your own display name, so you can use an alias or even leave it blank if you want to, so this shouldn't cause any problems. If anyone does have any comments on this, please leave them below or on the forum.
