No, PM means Prime Minister. Wait, that doesn't make sense... Maybe PM means Post Meridiem. No, that makes less sense. Is it short for Purple Monkey (Dishwasher)?

Seriously, it means Private Message. Just click the Lock icon to the right of any of Rikter's posts, but first you need to enable PMs on your account. Go to the Profile menu and turn on 'Allow Private Messages'. You'll know it worked because you'll now have the Lock icon to the right of your own posts.
