Waiting Room is a page for guides to find either guests or trips to support.
To find guests to guide, go to "Find a guest". Guests who have completed Journey Outline will be listed on Find guest page. Find the one you want to guide and become a friend with and send a Draft Plan to the guest.
To find a trip to support, go to "Join a trip". Booked trips are listed on this page. Leave a comment and discuss with the main guide to join the trip. It might be a good starter before becoming the main guide.
