Lunar you click on "show link" near the bottom of the horse's profile to make sure the numbers are in there and then just copy and paste the url into chat. It'll come up all long when you're typing but change itself when it's posted
How do I share a link in chat? IÂ’m on my phone but am super proud of the mare I caught today. IÂ’ll doubt IÂ’ll have such good luck next capture party
