1. I had no idea I wasn't already a member (likely because I can see the LJ posts, so until I actually clicked on a link within IJ that didn't work, it never occurred to me). However, I imagine I might need membership in order to, I dunno, see my own dang fic's comments.
2. That said, as I was scrolling down the comm for a mod post, now aware I was not seeing locked content, I cracked up a bit at the fact that there is an unlocked post for a PG fest fic which has a rather NWS icon (it's the one that is I guess from the same image as you have here, but scrolls down Harry?)
