I don’t know if this can be done, or what the technical terms are, but here is my idea.
Can you link the chat somehow in the forum? I have been seen live news scroll across the screen before. (Not here or Disney forum) Could this be done from chat for those “in the park” questions?
That way if you are in the forum you can see what’s being posted in chat and respond if you can help.
That way there won’t be crickets over there because everyone is here.
