Here is how to become a supporting guide.
1. Find a trip from "Trips to support" page
In Waiting Room, there is a list of trips that you can join as supporting guide. First, select a trip and click on Apply button to leave a comment. If you are selected by the main guide, you will be invited to a chat with the guest.
2. Become a friend's support guide
If you already know someone who has a booking in Huber, you could talk to the guide directly and ask the guide to invite you as a supporting guide.
To be a support guide, you need to become a friend with the main guide. Go to My Friends and search with the name or profile ID.
