In Firefox on a Mac, it is easy and convenient. Click Edit, Tab, and you are editing the title.
In Chrome and Firefox on Windows, you need to hit Tab three times because the Last Post Username and Timestamp get the focus first.
My recommended solution:
Add tabIndex="-1" to the two <a> elements inside the lastPostInfo block. (Maybe just for those who can moderate.)
Is this a bug or a suggestion? I think this is probably a bug since they way it works in FF is how I would expect it to work. EDIT: Now that I see it only "works" on Mac Firefox, I'm less sure. Move this to Suggestions if it should be there.
