HI Sandeep

What I've done right now is a double entry like system.  So _I_ store the
people who like my page.  And I also store the pages I like.

In order for people to be able to add the second record (which isnt
strictly necessary but a nice to have) I pingback to their URI

Pingback in our system is very simple, just like email.  It has a to a from
and a message.

A couple of things I need to know:

1) How can I identify and then authenticate a user on activity web

2) Once I have added the like, how can I send a pingback message back?
