To answer that good question (a year later I'm sorryDX), you'll have to create your own book or group chat to do those. Personally I recommend choosing the party leader's account to be the place where you guys create a book for the quest. If you just want to go a group chat, there's discord, skype, and large roleplay sites that allow group roleplays to be created and used. I'm no longer editing the book, so feel free to use these strategies or whatever else you creative people may think of:D
