Voting & Review app ?

Hi All, Does anyone know of a GPL web application that allows people to add the names of software tools to a list with a short review/rating ? We're trying to work out which desktop linux tools everyone uses and the best thing would be for everyone to enter their own favourties (via a web page) and score them.
