Here's the deal: The site's fixed! Yay!
If you haven't yet registered, you can now do so without problems (it works, I checked). Just create a username, click the link in the email you will receive and log in. You're in!
If you have previously registered a username, you have two options: You can reregister with a new username (you'll need a different email address than the first registration), or you can manually change your password using the "reset password" option found when you click "Forget Your Username or Password?" on the right.
I can also reset your password for you, if you'd like. Just email me (tzillerATgmail.com). If you need more help with this, email me as well.
I now expect many comments in this thread. Make me feel better about my blog! Do it! DO it!
