Small bit of advice: Link the game or give a brief description (preferably both).
Also, assuming it's this game: https://www.warlight.net/MultiPlayer?GameID=9709697
Real time games are hard to fill if they have 27 slots. Diplomacy games also tend to be a bit of a major commitment, so with 9 minute boot, the game could easily go on for as long as 7 hours.
If you want better attendance for your game, either make it multi-day or have fewer players.
