I am new to developing in una and would like some help finding where I can find the code variables for me to be able to get logged in users name, age etc. in code

I am using the credits module, on the dashboard menu it show total number of credits the user has. How can I get that to show the total number of credits in other places of the site. What code do I need to use when making other menus that will also show number of credits

When you stroll my site profiles the profile shows 2 times..
