*nod*  for the reason that saxxydiva stated, you 
can't login with your registered nick unless 
you're signed in, so if you're not signed in, you 
warp it.

In my case, half the time I have an ad/cookie-
blocking proxy running, so it's an extra pain to 
turn that off to be able to login properly.  If 
there were a password field as part of the 
message-posting form, so if you forgot to login, 
you can do it at posting time (please, Yann! ^^), 
I wouldn't warp my nick at all.
