Also, I noticed last night before I fell asleep that you were posting these, but hadn't added one to mine. I was starting to think the word "question" counted. Maybe it is just me but Rule #1 seems a bit unclear. I read it three times after seeing your posts and genuinely wasn't sure what that second part of the first sentence was saying. It sounded to me like it was saying the title must reflect the questions asked.
If the title must be a question then it might be more clear if it was worded like:
1-All posts must be legitimate questions, and all post titles must be phrased as a question.
