Before it was very easy, now apparently you can not do!
that's the problem I do not have that button, I'll just check, thanks
Go to your profile, scroll down to your friends list, and there is a "send invite" button. Click that and a it will ask you to type in an email address :) Hope this helps.
which is not the reason, but does not appear to invite someone?, just tell search facebook! thanks!!!
Well, 3 years later, there is no "send invite" link/button.
