Welcome to the new SemperVigilans.net!
Please follow the link to the forums. Ideally, you should use the email you originally used to access our old site and tell the forums you want to reset your password. If you don't know your email address, Galena, Fuggle, or Ligea can help you. You can also set up a new account, but it won't connect to your old posts.
Be sure to check your spam folder if you don't get an email right away.
