There's a message with each post in the forum which says :
"Your IP address is shown only to you and moderators. Remember that this information is not identifying, and that most IPs change periodically. You cannot see other members' IP addresses, and they cannot see yours."
But if you go to the history of a page in the Playground, and then put the cursor over a username, you can see the IP address of this person.
Is this supposed to be?
