How to remove Mafia Wars access to Facebook Chat

After having a chance to test out the Facebook Chat feature in Mafia Wars and understanding the risks to my friends if my account was ever compromised. I decided that leaving Mafia Wars with permissions to access the Facebook chat was a risk I just wasn't going to take!

So How to remove Permissions from Mafia Wars

Step 1 - Account -> Privacy Settings

Step 2 - Edit your Settings in the bottom left corner

Step 3 - Edit Settings (Top Left)

Step 4 - Mafia Wars -> Edit Settings

Step 5 Access Facebook Chat -> Click Remove

And your Done!

 Now Zynga no longer has access to your Facebook chat, and cant send messages on your behalf
