I am the pen name for any anonymous misfortunate hero writer.
My password is
"story", like my username.
Of course, malicious admins can still theoretically track you down by your IP address, so if you want to be super-safe, you can use an anonymous www proxy website like
http://www.the-cloak.com -- and if you want to be even more anonymous, you can use
http://www.torproject.org -- maybe even post at an irregular time so we can't identify you by browsing behaviour.
