To insert a single inline star rating inside a post just type <code>[usr 5]</code> where 5 is the rating/amount of stars.
To insert a tabular list of star ratings inside a post just type <code>[usrlist "Pizza:3" "Ice Cream:3.5" (...)]</code> where the first value is what you want to rate and the second value is the rating/amount of stars. Your list should consist of more than 1 key:value pairs.
