Hi Yuru, to participate in live streams for members, you need to join the YouTube channel AcademicEnglishHelp. This membership is managed by Google, not us. You need to click on the ‘Join’ button beside the ‘Subscribe’ button. If you do not see this button, it may be because you are using and apple device or because it is not available in your region. If this is the case, send me an email and I can instruct you further.
