Did you know about the"Others" folder on Facebook? (Milan)

Hi, I only just discovered that Facebook has a folder next to your inbox called "Others".
This "Others" folder contains messages sent from people who are not on your friends list.
The problem is Facebook do not inform you when you receive messages in this folder!!!!
I have checked and I have messages that were sent to me a long while ago! Some important ones too!
This "Others" folder is hard to notice because even though it is right next to your inbox the word "Others" is in a light faded out grey colour! So quite easy to miss it!
I thought I would share that with you all incase like me you didn't notice that it existed.
