Okay two request. I have searched the boards (but as a beginner I probably passed over the right answers), and haven't found how to do these two things.

1) On the registration page I'd like a set of hyperlinks that open to new windows whose urls have a UserID on them. (i.e. the url would be http://somesite.com/UniqueID=____ the blank being their specific id or registration #) I found this line on the registration page:
$newid = $newuser->getVar('uid'); And figured something in there ought to be what I can add to the end of the url.

Basically the link is for a site I'm an affiliate with so I need a unique id so I can track who completed an offer on the affiliate site. make sense? I hope.


2) I'm designing this website for my college. I only want students at my college to be able to register. SO, when checking the registration form, I want it only to go through if their email is _______@mycollege.edu pretty simple huh?

thanks.
