* to register your image for your email at gravatar.com, you need to give them
your email address, which is the same as you use in your wiki user profile.
-* we try to avoid exposing the referrer URL to gravatar.com, but this only
- works if your browser correctly implements rel="noreferrer". If it does not,
- your wiki item URLs will be exposed, so they will roughly know which people
- read or work on which wiki items.
+* when the wiki displays an avatar image on some item / view, the URL will be
+ exposed as referrer to the avatar service provider, so they will roughly
+ know which people read or work on which wiki items / views.
