Make Plugin or Customize Theme

Hi, Would you please review my wordpress? http://www.AutoMobilest.com (Q and A theme) I want to setup like this. Everytime my visitor put their question, my site directly will answer as very first person, and this answer must rotate with around 5-10 alternative answer (this quick answer rotate not rotate under other category, but for one specific category only). Example, on car insurance category; the quick answers will rotate just under car insurance category only too, then this quick answer will occurs as third or fourth answer again. Not just answer rotate, but username will rotate too to make other answer again use different name. Also, my avatar not working.

Kindly you owuld to review and help
