Another thing that has been added to everyone's profile is your "Visitor Message" which people may want to fill out. This is a message that people who are not registered for Pet Talk, or are not logged in will see.

If you click on my profile, you will see mine for an example. Everyone can fill out thier own message that they would want a lurker to see, maybe includng what pets you have, things like that! You can also leave someone messages on thir "visitor message" page, but I believe that message is public, so don't leave anything you wouldn't want a stranger to see.
