As a Level 2 Member Plus you will have the ability to prevent users from streaming in the main lobbies of a specific room, while still leaving them the ability to chat and play, without interrupting their streaming on Twitch. The streamdisable privilege works when you type in the command followed by a specific user name.
e.g. /streamdisable Bill streaming non-Voobly games
Once a Member Plus enters this command in the lobby, the user named Bill will have the streaming icon removed. Once the user is streamdisabled, you cannot change it, until the player starts streaming again. This is especially useful when a particular player is streaming something inappropriate and you want to immediately stop that action. Once the user is streamdisabled, you can then talk to the user privately and explain why he/she should stop a specific unacceptable action. Use of a streamdisable is preferable over use of all other privileges, not including VOICE.
