Adding an adventure module to another game.

Is it possible to add a new module into an existing game? Or will I have to create a new game using the new module and then invite my current players to join the new game (which will be a bit  of a giveaway for them :( )

Hi David L.,  No, only Addons can be added to a game.  As you have a Pro account you can use the Transmogrifier to port elements of one game into another, but it is time consuming to do that for more than a few items. If the adventure is large I would port the players and their characters to the new game.  Regarding the giveaway, you can rename it, and make the default page nondescript. Just tell them you've pulled in some other stuff as a resource but you'll have to do this thing. 

I like  your sneaky  way of thinking, Gauss :) I think that is the way I will be going, thankyou!
