Regarding anonymity, Network54 has a record of what email address you have associated with your logon name. You can go to "my account" to change that -- at https://secure.network54.com/My_Account/Account/Edit

If you are logged in, when you are typing a message, each post by default tries to put an email address right above the message-typing box. You can manually delete it with every post, and leave it blank.

or you can go to "my account" and change your profile to an email address that you dont mind people seeing. Such as squaloree at anonymous.com -- or whatever. Something that wont violate your privacy.
