Today is the first of the month. To me that day has an odor. It’s a distinctive odor, the odor of answers. Questions and answers. Come one, come all, ask your questions and they shall be answered. No realm of knowledge is off limits. Efficacy, intelligibility, and even grammaticalness itself are not guaranteed, but answers are.
I don’t mean to reiterate the double redundancy of repeating the same thing over again more than once, but you can ask literally any question you like and your question will be answered. Put on your asking caps and get asking. Post questions to comments, answers will follow.
