This afternoon, NSindex compiled a list of all known banners. After proofreading the banner ID codes, it has come to our attention that there may be two or more hidden banners:
1. https://www.nationstates.net/images/banners/l27.jpg
2. https://www.nationstates.net/images/banners/t7.jpg
Can anyone please explain the names and criteria of those hidden banners, and when they were retired?
Best,
