Go to edit personal information and you can choose which email address is displayed on your userinfo page.... your actual address, your livejournal.com address (for paid users), both, or neither. The "neither" choice complements the "Show contact information" option because now you can show your ICQ/AOL info without showing an email address.
Anyway, you get the point. The next few days will be more exciting as far as new features/options go. Today was a boring day.
