We're happy to announce that we've added SSL sessions for Tier 2 ad free subscribers. Currently this is only active on the main news site, the forums will follow shortly.
Even more reason to subscribe
Inevitable answers to questions:
Q: Why isn't it available for everyone
A: Because most of our ad partners don't support SSL delivery.
Q: Why not look for a different advertiser?
A: The certificate wasn't free, nor the work to implement it; therefore a Tier 2 adfree perk.
