I'm working on a new feature that allows people to share items. To do this i'm overlaying a modal on our site with 10 e-mail address input fields.
As you can see, because of the spacing on this modal, the 10 inputs overrun the screen space (this was taken on my 22" 1680x1050 monitor).
To overcome this, I'm wondering if it is better to put these into groups of 5, so on the first time the user clicks and is given 5 input boxes and they submit the form. the main underlying page will then display "send to 5 more people". or if any are unused in the first 5, the main underlying page will display "you can still send to
x more people", with the modal populating with 5 or fewer inputs.
