BYOND Members may host the game for others to come play.
If you want to customize your server beyond the basic hosting admin options, you'll need to get the Darke Dungeon Gamemaster subscription at http://www.byond.com/games/Shadowdarke/ DarkeDungeonGamemaster. GM Subscriptions are $15 for a lifetime subscription, or $13.50 for BYOND Members. Remember that even if you are a Gamemaster, you must have a BYOND membership to host the game.
I encourage fans to advertise the release in any other guilds or venues which might be interested!
