In facebook, when i goto "find friends" page, it tells me to put in my login information for my email, e.g.- yahoo, gmail, hotmail etc. After which it gets all the contacts from my email account. How does it do this? I want to design my own system like this, but am not sure where to start. Any help will be appreciated.

If your using php, I would recommend OpenInviter. Does most every major email and social network out there.

I believe this is done through use of large email providers API's for retrieving contacts. For example, Gmail contacts.
