I am trying to add a custom field to the wordpress user profile page. For instance if I wanted to add a field where the user could put in their Linkedin, or Twitter user name, then use that value whenever the user posts a comment, or if the user is an author, to add that value in their posts.
I have a forum (bbpress) integrated so I would also like to use this value to customize the users avatar in the forums.
I am looking at the way WordPress uses Gravatar. I would like to do something similar. However, I’m not sure where to start. I’ve written a couple of shortcode plugins in the past, but nothing this complicated.
Anyone have any ideas on where I should begin on this?
