A guide is simply a member who provides comment insights and advise on your readings and portrait. People who are adored the most, leave the most rated comments (insights) or have the most TarotRoom points are easier to find.
Members can leave comments on readings or portraits in the Tarot Room flow. If you really like a member, adore them (click heart to make it red). Soon you will be able to search for friends and family by entering their nickname, for now use their exact email address. Send them an invitation to join and then click on the heart by their pic to adore them. They will show on your feed and you can filter with only your adored members.
You too can leave tarot comment insights on people's readings, and tarot portraits.
