Ok so all you guys have a picture when postinbg and a user name.
Beneath you user name there's always another message like Ug's biggest pimp (to set an example) How do i change this? i'm not sure if this is the right place but couldn't find the general info forum.
Also could it be that i already have such a thing but I can;t see for myself, because i also have problems not seeing my user picture.

Look up near the top of the screen, along where the search bar is, look left, and control panel is located there. So just look up near the top left of your screen.
