A very minor quibble, but when you're adding a message and you've typed your nickname in, if you're mouse-averse like me you use tab to jump to the password box. I'm pretty sure this used to work, but now tab takes you to the 'Click here' link. I then often absentmindedly type my password, hit return and get transported off into the ether!
Any chance of getting the tab order changed?
It only bugs me when I'm at work when I tend not to log in, so my nickname and password aren't populated.
