I have made an application on facebook, i have added link share option, comment for the link and like for the same link. Now what i want is the person who is generating the link can also tag his friends. Is it possible?
See my previous answer to this question Facebook Graph API Post with_tags option you need to specify a 'place' to do this as far as I'm aware
EDIT****
According to the developer blog, you can now use mention tagging which might be what you want https://developers.facebook.com/docs/opengraph/mention_tagging/
