How to display user nickname in home page?

i have some problem to display user nickname near his profile pic. How can i do to show automatically his name on the bottom of the homepage and make it editable in future?

Hi Federico,

This is very simple ..You should have a column User_Nick_Name in may be any user extension table and than get it from the table based on the user id (on login) and show it in a disabled text box , also to edit it you can keep a link beside it enable the text box on click of link and than show the save link . Write you code to save the changed name in db.
