How to add friends from a email list?

Hello everyone,

I been on facebook for about 3 months and i been building my network of friends since then but its slowly growing.

I heard there's a option that let's you upload a list of e-mail and it will send those people a friend request.. is that true?
if so, how come i do that?


thank you in advance everyone!
