1.  I would like to know how to restrict one email per registered user. I had someone from the middle east try to make 3 accounts with all the same email within 30 seconds of each other. Ok... just got an email.... its now up to 4 accounts... errr.

2. Then how do I ban the emails that come back discontinued etc...

3.  concerning faulty emails... is there some sort of module or revamp of the code that will prevent bad emails in any of the processes?

I wish someone would answer my question... I see people asking questions that have been answered before... but I can't find this anywhere.

well thanks... that was too freaking easy.

What happens to the ones that have already been duplicated? Should I go in and take care of them myself...
