Thank you, your order has been received and an email from PayPal with the order details is on its way.
Sit back while we provide you with 32 referrals. You should receive your first few referrals today or tomorrow. You can check the progress on www.dropbox.com/account/plan. Sometime, some referrals appear as ineligible or waiting for install. However, rest assured; we will not stop before you have 32 verified referrals.
In the meanwhile, consider telling a friend about your Dropbox upgrade :)
