典典 accepts definition submissions to keep the dictionary up to date with modern trends. While we do actively do research and attempt to integrate the latest publicly available dictionaries, these user submissions are what keep us on the cutting edge.
When viewing a dictionary term, there is a "+" button below the current definitions. Clicking on that button opens the form to submit a new definition for that term.
Accepted definitions are logged under your user's profile, as is the your acceptance rate. Any definitions you have submitted will be listed with your username next to them. There are leaderboards for both of these statistics.
