I'm not sure if this is the right place to ask or if anyone can help out, but I'm in a situation where I have a lot of folks playing in a game, and would like the ability to disallow everyone, except for the four players currently playing, from typing or using macros in the roll20 chat. I can't seem to find much in the way of chat permissions here except for CommandShell, but I'm not sure that's what I'm looking for. Thanks in advance for any advice!
