Every day, people send more than two million Pins. Sending a Pin is a great way to let someone know you found something they’d love. We wanted to make it easier for you to have a good old fashioned conversation about those Pins. So now, when someone shoots you a Pin, you’ll be able to reply with a message or send a Pin back!
In thier official blog post Pinterest also announced that you can also send Pins and messages to multiple people. Say you’re organizing a camping trip with friends—try sending Pins to the whole gang so you can figure out where to go and what meals to make. If you need a reminder of who’s bringing what, just pull up the conversation right from your notifications.
