We've put together a new forum on the main index page titled "Target Hits (Game Submissions)" [maybe subject to revision]. Within you'll find unique subforums for each game type containing game submission threads as well as each active game queue. Things are organized and tidy now. There's even a new game type in there. We'll see if it sticks.
To submit a new game, simply stick a submission thread with details about your game (to whatever extent you wish to reveal them) in the forum associated with your choice game type. Don't worry about repeating the type in the thread title! Also, you may want to take a stroll through those forums; you may find games you had forgotten you submitted half a decade ago.
We still have The Don's Hideout. We'll just use this space for general discussion of Mafia now.
Any questions or concerns, let us know. Thanks gang!
