Update: I <3 SideJobTrack. That’s all.
(And please don’t tell me to set my TAB to go through links as well as form elements. That’s unacceptable; this isn’t Internet Explorer.)
The same goes for you too, Flickr, making me click through no less than two screens (1,2) to get in. I suggest a simple form on your front page with a username and password field, and two radio buttons: one for classic Flickr users and the other for merged Yahoo accounts. Should be pretty easy for that to forward to a script which determines what goes to which login server.
Come on, there’s nothing wrong with showing a few text fields and a submit button on your front page. It’s not a blight on your design, and it makes things easier for your users.
