I've seen a few people whose posts are just a quote of a previous post, with no additional text. Others are embedding their replies into the quotes of the previous person. The WYSIWYG editor doesn't work too well, so I have been using the View Source button from the toolbar (ctrl + shift + s or the button on the far right of the lower toolbar that starts with the font buttons).
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
