I want when someone registers or i create a user his profile information will be filled with default content i choose.
I found this http://codex.wordpress.org/Function_Reference/wpdb_Class#UPDATE_rows
So i have to update this rows
In wp_usermeta update description,aim and some more
in wp_users update the user_url
But i cant understand how to do it. Also to what function should i bind to execute this? I could not find any "user_registration" one
