I haven't got one in quite a while either, but if you want to see if you are *supposed* to be receiving it:
When you're in the "My FlyerTalk" screen, look in the box on the left next to the forums, headed "MyFlyerTalk". Go into "Settings->Edit Profile" and see if you have the option for "Receive Email from Administrators" under "Messaging & Notification" checked.
