You can participate with:

• no pseudo
• an unprotected pseudo
• a password protected pseudo (click on ">>")
• a password protected and email verified pseudo

The last method is the only secure way to protect a nickname on this server.

If a pseudo is not protected and verified, anybody else can protect it for themselves if they at least supply a password and an email.

A login must contain [3..40] characters, a password [5..40].
