Yes! We now offer in-app messaging. If you're looking to message a Host for the first time to ask a question, you can do so by clicking the "Have a question?" link on the Host's listing page. From there, ask anything you like!
Once the Host writes you back, you'll receive a notification and you can access the message by clicking the text bubble at the bottom of your screen while in the app.
Clicking the text bubble will take you to your Messages where you can continue to communicate with the Hosts you've been communicating with.
