Once a conversation has been created, you still have the opportunity to edit the name, attendee list, and more. To do that, first navigate to the conversation you want to edit from your homepage or your forum's homepage.
If you created the conversation, you'll have the ability to edit the name of that conversation, the forum it's housed in, the attendee list, as well as the start and end time. Make sure to press Update to save any changes.
You can also tap Delete to remove this conversation. That action cannot be undone and will send a notification to all attendees.
