Genisay#3590

I was not sure if this was the right section, but it seemed like the most logical one. I do not want to disable Tatsu all together because we use her to do dice rolls and other things for a DnD campaign, but the starlight festival prompts are becoming disruptive and no one is using them. Is there a way to turn this off so that I do not have to keep going back and manually deleting all of the posts every time people start using the server's chats?
