Use the Thumbs Up button to let a player know you think they're awesome! Give players you love playing with a Thumbs Up up to once every hour, and other players will know they're a good player!
Is someone you're playing with being a jerk? Do they have inappropriate content in their profile pics? Flag their profile - they'll never know you've flagged 'em, but we will, and if player gets flagged enough, we'll take care of 'em.
Did you flag someone improperly? No problem - just click on the button again, and it'll unflag 'em right away.
