Facebook Messenger lets you send messages to people you don't know and vice versa.

Chances are you are among the 500 million souls on this planet using Facebook Messenger on their Windows Phones. Today, Facebook Messenger received a pretty big update in that you will be able to send messages to anyone using the Zuckerberg social network.  By anyone, I mean even people you don't know and it works both ways. So you may start receiving messages from strangers, like it or not. This feature has been available on other platforms for some time and I have not heard horror stories, yet.

Here's what's new in this update that brings Facebook Messenger to version 9.0:

• Improvements to make the app faster
• Now you can message people even if you're not Facebook friends
• Tap People to sync your phone contacts
• Enter anyone's phone number to start texting them from the app
• Add colorful drawings and text to photos from your cameral roll before you send them
