visitor stories

Hi themeforest members

I am looking for a good looking (wordpress) theme that lets the visitor post his own story just like on fmylife.com. No registration, no clumsy form with a hundreds of steps to go through. just a simple and smooth theme that lets the visitor post their thoughts.

Is something like that already available here?

Best regards raphy

ps. some terms of how such a system is called would also already help…
