To qualify for Yahoo! Personals' 6-Month Promise:

• You must be a U.S. subscriber who has signed up for a Yahoo! Personals six-month subscription on or after May 22, 2008.
• You must post an approved, searchable profile for the entire time of your paid six-month subscription.
• You must display an approved primary photo for the entire time of your paid six-month subscription. A caption is not required.
• Using the Yahoo! Personals email feature, you must contact at least five different people each month during your paid six-month subscription. Initiating an email conversation or replying to an email counts toward the monthly minimum figure. Icebreakers, however, do not count. If you contact more than five different people in one month, the additional people (over five) do not count toward the monthly minimum in subsequent months. A month is defined as 30 consecutive days, As a record, you must keep your “sent” emails for at least 31 days after you send them.
• You cannot cancel your paid six-month subscription at any time while it's in effect.
• If you do not find someone special by the time your paid six-month subscription ends and you believe you are eligible for our 6-Month Promise, you must contact Yahoo! Customer Care by email within the 10-day period before your subscription automatically renews. (Don't worry. We'll send you a reminder email about the renewal process.) You have one opportunity to discuss your eligibility with Yahoo! Customer Care, whose determination about your eligibility for the 6-Month Promise is final.
• If you are eligible for our 6-Month Promise, you must use it immediately after your paid six-month subscription ends. Time cannot lapse between your paid subscription and the free six months.
