PSA: Why you may not be able to see content under the new settings.
So, if you notice a lot of posts on your flist that say, "You are about to view content that may only be appropriate for adults," no, these are not test posts from your flisters, trying out the new adult content settings. Because if you go to look at their ljs, ALL their posts are now under a cut stating this same thing. They've changed the settings on their ljs to indicate there is adult content in their ljs, and the reason YOU can't see anything is because you haven't registered your birthday with lj. (Like me, until 10 minutes ago.) Make that change, and, assuming you are not a minor, the content will be revealed again.
