Hi, so, I'm trying to make a website that each member has it's own db and settings, which is something like facebook, or pandora, that each member have their own page. they can save settings and have their own preferences on the website. I'm using PHP and Mysql. I have a main page that when you enter has a login form on the top but I want to make it in a way that when the user logs in, the form disappear and also the page loads the user's settings and needed data. How should I do that?
