Jquery Shoutbox
 

Hey guys i need some help with this shoutbox. I thought the whole thing was sound until i found this problem. If you go onto the shoutbox in your browser and you set your username and then change it... its supposed to say but for some reason if you change your name more than once during that session it prints the welcome message +1. You'd have to see it for your self. Please help me out. the url is http://www.slappyjaw.com/chat. enter your username and then change your username a few times you'll see what i mean. Im stuped so far. its as if the ajax request is being sent +1 one each time you change your username or logout. Thanks in advance.
