A way to log in finally

A number of people have created accounts here to avoid the necessary evil to reduce spammers that is the CAPTCHA thingy. But you may have noticed that there was no way to actually log in. Oops. Now there is - on every page you should now see a login / register link. I'm still trying to figure out what additional benefits I can bring to registered and logged in users...but for now, if you are logged in, you'll no longer have to solve the math question.
