You know Grandma will have questions after you text her a sign up invite for laser tag with the grandkids.
To make it easy for her to respond, when you compose a text message in our Messages area, you will see the option to include your reply-to info. If you have a phone number entered on your account Settings page, the system will pull that as the reply-to. If you do not have a phone number in your settings, the system will list your account email address as the reply-to.
To change your phone number settings at any time, click on the circle image of your picture or initials in the upper right corner of the page when you are logged in and select Settings. Once you've updated your phone number, click the Update Profile button at the bottom of the page.
