For getting new account you have to anonymously (without sending any authorization data) connect to NNTP server and send message to local.regreq group. Message should be something like:

Hey! Please create account for me. Login is “MYLOGIN”, email is “MY@E.MAIL”

Warning: this group is moderated, so you won’t see your message in it after posting (as anyone else). This message will be mailed directly to administrators via email.

After getting password via email you can configure your account in your newsreader.
