The feature was completely replicated and improved on the WpStream plugin since it was a popular request from many users that were not using our experimental theme. You are more than welcome to try it out with your free plan, all features available! Please see the instructions in this post – you will also be able to check out our video tutorials https://wpstream.net/how-to-enable-regular-users-to-broadcast-via-the-front-end/
We also welcome all users that have worked with this feature to comment on their experience. We would appreciate any feedback!
