[Plugin: Register Plus] Variables for custom mail

Hi there!

I installed this great plugin! I really love the CAPTCHA thingy.

But I have one tiny problem with the custom (HTML) mails.

Some variables aren’t returned in the email.
Therefore a new user can’t click on a URL, because there isn’t an URL, nor does he see it’s username, because PHP returned null there as well.

Is this a bug? I only installed, and activated it.
