Ok, that's new. The user shouldn't get an email with an activation link. At least an activation should not be successful this way.

He didn't try to click. We don't know what would happen.

If you are an admin, go to your personal settings, point "E-mail notification" and activate at least "once a new user has signed up". You'll get an email in the future, when a visitor registers him-/herself.

OK, I'll try this.

Thanks for thinking about it.
