Little bug report :
I even don’t know if “bug ” is the right word.
With <3.01 when I was connected (I'm admin) I could answer to a comment without the connection form displayed under the comment form.
With 3.0.1 in this situation (connected as admin) even if the form tells me "connected as xxx" the form is displayed as if I was not connected (but if I don't fill the form the comment is send ok)
