We only require an email address and a nickname to sign up. We ask for the email address mainly as a way to fight spammers. The spam bots who try to sign up for the site generally don’t answer the verification emails sent out – it’s stopped hundreds of bogus accounts. If you are concerned about privacy, there are many services you could use to create a “throw-away” email account that you only use to sign up for this site.
Finally, there are digital footprints – IP addresses, browser types, etc. Again, to serve you a web page, we must know where to send it. (Although if you’re feeling extra paranoid, use TOR.) We reserve the right to turn on analytics to track what parts of the site are getting the most use, but we keep them off most of the time. If that bothers you, you can turn off those cookies by clicking the blue cookie in the lower left-hand corner and turning off analytics. Viola!
