This is something that I have been wondering for a while... Why don't we want to have the username/password textfields on PM's frontpage?
They would take so little space... and users like me who login everytime (because they clean their cookies a lot :-) would not have to load a separate page.
To make it more fun, I guess it would even be possible to use the search text field for login, where something like "myusername/mypassword" would be automatically recognized as a login.
