New user registration redundant email check
Hey everyone. I'm fairly new to tikiwiki and have a new site ccpathfinder.com which is about one month old. Over this short amount of time I have configured tikiwikis options to what works for my websites intent, but there is a "flaw" or missing option in the registration process which I would like to add. Or maybe someone has already reworked the php and related files to make this work.
Essentially I want tiki to check existing users email address against the new registering user to see if the email address they are using already exists, and if so, to throw a registration error explaining that the email they are trying to register with already exists not allowing completion of said new user registration.

I've been having a problem with people registering multiple users with the same email, who are basically searching for sites to add links to their own site, who have no intention of providing any useful information for my own sites intent.
I have been checking on my own accord the redundant email problem and disallowing creation of offending users, but this is a pain and I am sure that many other people would be interested in adding this feature to their own tiki site.
Help is appreciated. Thanks.
