hi, i have run into a slight problem. i have made a login system using php and i wish for the user (once logged in) to have their user name diplayed in the header of my site on all pages the visit whilst they are logged in. or if they are a guest for it to display 'guest'. i just cant remember where abouts i have to put this piece of code and what needs to be on each page. could anyone give me a clue as to where it goes and what it needs to be
thanks in advance
