Forward to your friend

Hi, I want to create a Signup form, and I want to ask my emailers to invite their friends, instead of them typing their friends emails one at a time, is it possible to show an import your contacts dialog for yahoo, gmail etc ? so they can select multiple emails one at a time?

Thanks

We do not currently have a method of importing contacts into the form in order to send our invites.  The emails would need to be entered manually.
