To set arrival rooms, you need either the moderator or operator role.

When you enter the chat, by default, you arrive in the Lobby. However, a moderator or operator can configure other rooms to serve as arrival rooms.

When editing a room, you can mark a room as arrival room. Users who join the chat will automatically join all rooms marked as arrival room.

If a temporary room is set as arrival room, please note that this status will eventually be lost as the room is removed when the last player leaves.

Tip: It is usually easiest if only one room is assigned as arrival room. Thus, if you create your own arrival room, it might be useful to disable the setting for the default Lobby, or to remove the lobby entirely.
