confirmation email for user signup

[eluser]Brad K Morse[/eluser]
If I was using php w/o CI as the framework, I would display a activation link within the confirm email like: domain.com/[email protected]?key=0301002020

I have not done this in CodeIgniter and was wondering how I would accomplish getting ($_GET) both those variables to pass into a controller function?

something like?

domain.com/confirm/[email protected]/0301002020

Code:

function confirm() {
$segment_2 = $this->segment...
$segment_3 = $this->segment...

// rest of the confirmation code
}
