email

I have read somewhere in these post that a user came up with a way to add an extension that would email the friends email address when post is made to his/her account or email the user that someone is inviting them to be a friend instead of "inviteing them"  I am particularly looking at the part where the system emails a user pesonal email when the dolphin user receives a post.  Can someone point me in the direction where I can find this

in other words email the member to their outside email address every time someone leaves a post or a message to their account.  I know I have read it I just cant find it.  They said it was free on expertzzz.com but I can't find anything of the sort
