Abstract: A channel graphical user interface (GUI) of a content sharing platform is provided for presentation to a channel owner. A request is received, via the channel GUI, to enable an online community option that (i) facilitates an online conversation between the channel owner and a subset of viewers of the channel of the channel owner on the content sharing platform, and (ii) allows the channel owner to control viewer responses that are permitted during the online conversation. In response to the request of the channel owner to enable the online community option, the online community option is associated with the channel in a data store, and the channel GUI is modified, the modified channel GUI presenting an online community GUI element representing the online community option.
