I'm brand new, so sorry if I'm missing something, but the pinned posts in the General Discussion tab all seem to have lost their original posts. I tried to read the "read this first" threads, but the only posts in there are "thanks!" etc. I checked other threads and I'm able to see the first post.
Also when I clicked on the author links of those threads, I get a 404. So assuming the accounts (and their posts) have been deleted? If so, maybe someone can unpin those threads, or maybe create new ones with the relevant info?
