Acronym - Posting For A Friend
Posting, as a favor, to a mailing list or a forum for someone who is not on the aforementioned mailing list or forum. The friend does not have to sign up to get the benefits of membership. The poster writes "Posting for a friend" with the hope that he will not be tied to the post, nor get the further inquiries. Most of the time this does not work.
