This page describes the behaviour of livechat versions >= 10.0.0. There were some changes in the way we manage access rights for Peertube administrators and moderators.
You can use a chat bot, that will help you for moderation.Check [the chat bot documentation](/peertube-plugin-livechat/documentation/user/streamers/bot) for more information.
You can access room settings and moderation tools using the [chat dropdown menu](/peertube-plugin-livechat/documentation/user/viewers) at the top of the chat.
Starting with livechat v10.0.0, Peertube instance's admins and moderators have no special rights on rooms by default.However, they have a special button available on top of the chat: "{{% livechat_label promote %}}".Clicking this button will give them owner access on the room.
You can use [ConverseJS moderation commands](https://conversejs.org/docs/html/features.html#moderating-chatrooms) to moderate the room.When you open the chat room in full screen, there will also be a menu with dedicated commands on the top right.
To enable or disable this feature, use the [chat dropdown menu](/peertube-plugin-livechat/documentation/user/viewers), open the "configure" menu.In the form, you will find a "{{% livechat_label livechat_configuration_channel_mute_anonymous_label %}}" checkbox.
When this feature is enabled, anonymous users will be assigned the "visitor" role.You can change their role to "participant" if you want to allow some of them to talk.
