Pull contacts from users' email accounts

This is very nice module. It allows a site to “self-promote.” I think it should be allowed to pull contacts from users’ Gmail, Yahoo, and Hotmail accounts. So many users don’t remember their friends’ email addresses off hand and it’s monotonous and tedious to enter email addresses one-by-one. Users would be happy to invite their friends if it’s easy to do so. Please allow this module to pull massive amounts of contacts from users’ email accounts to send invitations.
