Upgrade special offer

I'm confused about your special offer. I've been a yearly Premium subscriber for a couple of years now. Am I to understand that if I do nothing and remain a Premium member, the price will rise in August to $159 year, and that becomes locked in forever? Or do I have to upgrade to Silver for $319/year? I'm a bit confused by the options and ramifications.

Thanks,
Doug Lufkin

Sorry about that. That email was actually only intended for free users. You will keep your existing low prices as long as you are a subscriber. All existing subscriptions are grandfathered. The new prices only apply to new subscriptions.
