Please let me assure you:
- It's quick and easy!
- You won't get unrelated email as a result. I will email once in a while to let you know about major additions to the site, but that's all.
- You can always easily un-register.
I hope the registration won't discourage you from posting responses that you otherwise would post. But if it does, you can always email me directly with your comments, email@example.com, and I will post them for you.
