Thanks for the replies guys. We’re aware that group chat is not a full-feature (and there have been some regressions over the past few months, aka /ban no longer working).
One of our reasons for focusing more on host-mode than group chat is that host-mode converts a channel page into a community page. Now a ‘channel’ can become popular and never broadcast. It allows us to focus on improving the channel page, which helps broadcasters and communities simultaneously.
