Why is my valid email address required for Wacktrap registration and use?

We’ve gotta be able to reach you when necessary. When you first register, we need to verify that you're human and not a bot. More importantly, there are times when you're gonna need to hear from us.
 

Yes, both your Wacktrap username and password are case-sensitive. Why is that so important? If you've used a cap in your password or username, you've gotta be usin' that cap in the exact same spot or you won't be gettin' in to your account anytime soon.
