To better this project, I would suggest using a type of grid on a form with the columns of Email Address, Hotmail, Yahoo, Gmail, YMail, Live, Rocketmail, MSN. You also shouldn't need to put the emails extension. Just the first part that you want.
So instead of
Chad@hotmail.com you would just put Chad.
It should look something like this
* = Available
x = Not available
________________________________________________________________
| Email Address | Hotmail | Yahoo | Gmail | YMail | Live | Rocketmail | MSN |
________________________________________________________________
| Chad | x | x | x | * | * | x | * |
________________________________________________________________
| Admin | x | x | x | x | x | x | * |
________________________________________________________________
Of course it wont line up in text. But I'm sure you get the point. At least that's what I would do.
