Configurable Player Feedback Database

I run an active gaming community (Vbulletin) and would like very much to have a database where players can enter in feed back about players they meet online. The database should be configurable, that is categories should be added, rating given and text feedback. Allow imput from web users but be secure from SQL injection and an admin should have to approve feedback before it is posted to a webpage and beable to edit it easily..
