Searchable Only By Paid Members

Submitted 12/3/2009 by Geoff

I noticed that when you add a new Question with Options, there are choices for making that data "Viewable only by paid members" and "Editable only by paid members".  I would like another choice which is "Searchable only by paid members".

I want everyone to be able to set the value on their profile, but I want only paid users to be able to actually search / filter by it.
