show specific content for each registered user in joomla 1.6

I am looking for a module/extension, or something that can help me to make a page/item that only one specific user registered can see. I would like also create a space dedicated to this user, where i can publish there pages and aticles.

Maybe using php and开发者_JS百科 the variable that contains the username and an iframe, but I dont know how to doit.

Thank for the help

GMAccess is a Joomla! component that makes managing groups and access permissions easy, you will be able to create a special group and add your user (via Joomla's user management) to it and manage which pages can be viewed by that group.
