The first post stopped after 45,172 characters (44k) according to EditPad... I wouldn't think that that would be incredibly high, but I don't know. (The complete post would be almost 75k)
But FWIW, something like that seems to be reference material. I would consider just creating a new content page and linking to it. I'm pretty sure there's a "blank" template or something you could use in the UBB files to plug this into...?
