I feel this is a concept that needs to be there on Squadhelp. In a few cases, there really are more than one deserving winner, however the complete lack of prize splitting results in one person taking all and another person who came up just short getting nothing.
Take the recent Farm contest as an example, the name “Clear Roots” was the clear catalyst for the winning name (By a different user) and the guy who suggested it got nothing except if the contest holder chooses to give him a nominal bonus or tip. However if prize splitting existed, both guys could have been sated with no extra liability to the contest holder.
This is also a concept that can be implemented for abandoned contests where no entries have been rated or where a large number of contestants have similar high ratings.
