retrieving user name

I need to create a link the the users profile home page. Can anyone tell me how to retrieve the users name in a variable that I could use in a URL?

If you are using PHP Code block then you can use the following code there to get user name:

return "Display name: " . getNickName($this->oProfileGen->_iProfileID) . " / Username: " . getUsername($this->oProfileGen->_iProfileID);
