This panel has options to offer anonymous commenters to register after submitting their comments, and to detect and protect email addresses in the comments.

If you check the Email addresses option, b2evolution will warn the user and prevent a comment from being posted if it detects an email address in the content. This is done to avoid exposing the email address to spam robots. This option is checked by default.

You can also offer anonymous users to register to your site by leading them to the registration form after they submit a comment. Check the Register after comment option to enable this feature. This option is checked by default.
