Each person can only write one sentence however. You can write a paragraph, but only as a way of hypothesizing what the content of an already posted sentence means (and then we'll vote on what to agree with). The content posted in a sentence will be definitive. Only through voting can we eliminate sentence derived content for the system.
From that, we'll see what we can come up with.
So yeah, post only one sentence. Or post a paragraph. This is per post - and you can't do both. If you have a question, you must explicitly say that it is a question and nothing directly pertaining to the system.
Creativity is one of the core stats.
