Referrals are very easy with YPC. Simply look toward the bottom of any profile whether in your Contact History or any Directory listing. Tap the [megaphone] icon to start a text message with a referral template that includes the web address to that person’s profile.
If the MegaPhone is grayed out, that profile is a basic profile. If this is the case, you’ll need to take a screenshot of the contact and send it as an image or download the free vCard profile, and send it as an attachment.
