If I were Idina, I would not sign at all right now and the fact that it is that important to people that she sign their freaking playbills in the midst of what must be a really tortuous time for her and her husband is, I admit, something I do not understand.
If you have the slightest compassion in your soul, you have to be more concerned about her safety right now than getting an autograph.
I am not pointing any fingers at any individuals here...so please don't flame me. Just making a general comment. Over the past week, since this hideous threat was publicized, I've seen a lot of the same questions about signing pop up on this and other boards and I woudl frankly be embarrassed to even ask that question right now.
