Whenever you refer someone to Offline:
You get 2 bonus credits* added to your account. Credits can be used to pick restaurants and eventually other perks/events on Offline.
The person you refer gets to skip the waitlist and will get their first month free (which is basically 2 credits)
There is no limit to how many people you can refer and all bonus credits will be applied to your account the same month your friend signs up with your code.
*Bonus credits are applied after the person you referred completes their trial and signs up. You'll see "Pending" on the referrals page here.
*You will not see members that you have referred but have cancelled. If you received bonus credits for them, you do not lose those, you keep them.
