Just wanted to css format the "please login or register ... " part and found out that it is inside the h2 tag!
The h2 tag is in this case generally used for the "Your answer" headline.
<div class="qa-a-form" id="anew">
<h2>Your answer</h2>
AND
<div class="qa-a-form" id="anew">
<h2>Please <a href="../login">login</a> or <a href="../register">register</a> ...
There is no way to CSS format this part, it always effects both.
