As far as the Q&A Community - having others ask you a question directly (like an "ask box") isn't a current feature of the site. If you want to answer questions on a particular topic, you can browse a category that interests you. Or just browse the site in general.
No one gonna direct a certain question to you, there is no such option here. People ask their question and posted in general for any one to answer, from these question yo an see what you know and answer.
Ok. How old are you? Are you a girl or boy? What is your favorite color? Do you like country music? How come they called them apartments if they're all bunched together? What state do you live in? Do you like cars? What kind is your favorite? Do you have any pets? Will you wash my truck for me? What's your favorite kind of food? What did you have for dinner? Have you ever been to a concert?
