The way these sentences are answered are mostly correct, or at least two of us think so. The first one seems to be a concern, but it's fine. It's a command and the subject [I] is understood.
It looks like the Oilers are going to loose tonight.
Don't Worry {about it]. [about it is understood along with the subject which in this case is you].
It's the 3rd one that is the problem. I think it is grammatically incorrect. If it said "Don't Forget Me]" that would be fine. I'm not sure what it means when it is written the way it is.
