This question is an exact duplicate of:
In any SE site, from my account page, I can see things I flagged. But in Area51, I can't see such option in my account page. How can I see the history of my flags or what action were taken etc.?
Area51 is a StackExchange 1.0 site and on it there is not any possibility to do that. You can make a feature request, but I think it will be not approved.
