Site security updates:
We have modified our site to store less personally identifiable information (PII) about our users to protect your privacy.
Our site now does not store your real name or email address.
We do still ask for your email when you create an account, and we send you one email message to verify your account.
But your email address is not stored in our site's database; instead, we store a strongly encrypted hash of your email that is used only to prevent duplicate accounts.
