Add {{Wikipedia:WikiCat/topicon}} to your profile to display this topicon at the top right corner of your userpage. If you wish to reposition it, use the code {{Wikipedia:WikiCat/topicon|30|8}}, replacing "30" with the horizontal distance in pixels from the right side of the page and "8" with the vertical distance in pixels from the top of the page (the line below the tabs at the top marks the "top of the page"). To use the topicon strip, add {{subst:Wikipedia:WikiCat/topicon}} (with the same optional parameters).
