The plugin would allow an admin to create a contest for predicting the final score of a game. The admin would create the contest by selecting team names for TeamA and TeamB, as well as a closing date for the contest, when submissions are no longer allowed.
As users enter the contest (they must be logged into the site to do so), the contest table is populated with rows. Prior to the contest closing date/time, a logged in user can not see any other users predictions in the contest table (they are obscured with a stock image or blurred out). A user can also edit their submission up until the contest closes.
When the contest closes, the table is visible in full, and can be sorted according to the rows.
After the game is over, the admin manually enters the final score of the game, which then displays in the top row of the contest table. If no user correctly guessed both scores, the table remains unchanged. If any users correctly guessed both scores, their rows are displayed at the top of the table, and the rows are highlighted in green.
