First be sure to end the recording or streaming.
To end your event or meeting, just click on the red X button at the top right of the toolbar. You'll be given the options to Exit Meetn, End Meetn for Guests, and Return to Meetn.
Exit Meetn will disconnect you and only you from your room. Anyone else still in the Meetn room will remain.
End Meetn for Guests will disconnect all the guests right away and send them to either the Meetn homepage OR the Exit URL. The Exit URL is another website you can have guests redirected to automatically when the guests exit the room. You can set this in the Menu > Room Settings > Webpage On Exit URL
Return to Meetn will simply close the menu and you'll remain in the room.
It's recommended to use End Meetn for Guests to end an event. The guests will all be disconnected, but your hosts and admins will remain. The waiting room is also turned on automatically so guests cannot re-enter the room. This gives you the perfect time to talk with your fellow hosts post-event.
