While I revealed my horrible math skills, I went in to finish visiting my TORniversary post on Off Topic on January 8th, and I can't find it! I've also done a Search Posts of all my activity this week, and there's no sign of it.
If it's just one of those glitches that happens now and again, that's totally okay! But if I've possibly done something I shouldn't have... I promise to be good and not do it again... but what would that be? :)
