Hi @KC1102 and @Silversitters
I thought I’d pop on and confirm that the owner you already have a confirmed sit with is notified when the second sit is confirmed. We would encourage sitters to signpost their intention to utilise duo sitter wherever possible. 
(btw happy cake day @KC1102 - that cake beside your user name means it’s your forum birthday - you’ve been here for four years as of today! Glad to have you here 
)
