Does anyone know what file I edit to change the profile preferences in regards to privacy in a user's profile fields?

I am trying to change the options that are available to the user when you select user preference for the user's profile fields.

For example, the current options are:

default
myself and admin
all registered users
friends
private
everyone

I'd like to greatly simplify this to be

Friends
Everyone
Private

Does anyone know where I can restrict the number of options or change this, specifically what files I need to alter on the FTP.

THANKS!

It appears that those options are hard coded in the drop down.

So there is no way to remove or limit them? If we have to comment them out , that is fine, but I need to figure out a way to remove.

Any ideas for us?

Thanks.

You can do it client side by using the attached jQuery snippet.
