Thank you so much to both of you for your testimony.
I wanted to ask a little about international models around monitoring online and these sorts of things, because I found an article, Ms. Arnason, in which you talked about the British model—this is from 2013—and expressed some cautious optimism about that. As I understand the British model, it's proactive filtering with the option for people to opt in to a wide range of different kinds of material. It's done currently on a voluntary basis, but there has been ongoing discussion about legislating.
I wonder if you kept up with the detail on the British model and can comment on how applicable some of those lessons might be to us here.
