Login using google-account

You should definitly make the "Login via google"-Button bigger. Yes, I know, it already _is_ big, but I still did not see it for like 10 minutes and at least 10 unsuccessful logins using the form and my google-username/pass... ;-)
I think the average user (and I hope I'm not the only guy with that problem ;-) ) is too fixed to the form-elements to recognize anything else as login-posibility. Maybe placing a link in the "login not found"-error-message would help...
