I have been enjoying the LOC Facebook posts regularly for some time now. I am not a Facebook member so I can't post there, but love looking at the photos, and comments as well. Today, for some reason, I can't access the site without signing in to FB. I have no desire to sign up/join. Did a setting get changed that could be reversed, so non-FB people can still enjoy the site, or am I barking up the wrong tree?
