Andy,
Here's my idea for a Jozi Chat
I think the GM's best course of action is to create a Twitch TV gamming channel. We then use the Twitch channel to host regular Jozi chats, Developer updates, and Possible game changes. One issue many players have is the antiquated GM to player sharing of information on the game. Doing your updates on Twitch once a month in a 10min or less update allows people to have more involvement. You can still post on the game update section, but due to the nature of twitch it would also allow people to join in and listen at random to your updates and comments increasing exposure to the site and mobile app. If your open to this I would be willing to create a channel and do the leg work in an effort to help the GM expand.
As for the Jozi chat, I'm thinking that I can create a survey monkey poll with the following questions (I would also provide the GM private access to the poll).
-What is your highest game level?
-What is your highest war level?
-How many wars have you won?
-How long have you been on Simcountry?
-What would you like to see changed?
-What Questions would you like to ask the GM?
This would allow me to compile a list of all questions and answers before the GM or Jozi chat. I would provide you a list of the most common questions for you to address to the player base, give you time to address any updates you have or maybe explain an update or change your making, and give a small amount of time for anyone live viewing the channel to ask a question.
