You're referring to the '10-day free trial' of Diamond premium membership?
I suspect it is just about the same as simply subscribing to Diamond, and relying on the site's one-time 30-day money back satisfaction guarantee (which, in the unlikely event you're unable to revive the site's interest in letting you try their 10-day free trial, would be a presumably risk free approach).
btw, I've been told that while the site does not otherwise refund membership payments, it will 'downgrade' say a Diamond membership to a Platinum by doubling the duration remaining for the membership.

ps. I heard today of 'prepaid cards', apparently that's a credit card you can prepay with a set amount of cash (available at places such as Wal-Mart?) which I suppose might be of interest to those with privacy concerns.
Posted in the help topic but i am getting no responses after even a few hours.... I missed the free trial of premium mebership by a few hours and would like to take advatage of this. Is there any way I can do this?
