Wow. You're welcome.

No need to disable...just don't use the places feature if you don't want to.

As for permissions: They are rather poorly described by Facebook when accepting, but you can read about them here: http://developers.facebook.com/docs/...on/permissions. Most are obvious except for the offline access. This allows an app which is not tied to a web session to use the api beyond a short time. Without it you would need to log in nearly every time you used the app. With it the app can use a token obtained to access facebook for discrete transactions until you invalidate it.
