App Description Field Comments.

How do I get permission to add comments in the comment section of an app's 'Get Info' Box?

This is where I usually put common shortcuts for an app. For example, you can see if an email address in something sent to you is a spoof by hovering over the address with the right mouse button clicked.

But I sometimes forget the trick so I like to not it in the comments section of a program's description field.

Now that I own a new mac and want to add these things to the program's contents box, I have insufficient status to do so. But I am the owner, user, and the one who bought the mac. So what do I have to do, to reenable comments in app description fields?
