Haha, I can see where you’re coming from when you say that posts of such dimensions don’t usually happen here. 
Apart from the Ultimate Guide, I can only think of @fallynleaf’s and @MissDagger’s level 60 post that didn’t fit into one topic post either off the top of my head. I suppose that would make us (more than) two peas in a pod in terms of writing posts that go beyond the limits. And I only know about the post limit because of one thread made by fallynleaf on this very topic, by the way.
