The URL of the article is what determines which username it defaults to. The left side of the screen shows the article categories. If the article comes from a sub-category--such as NEWS\POLITICS--then the username is the correct 3deedan. If it comes directly from a category--such as NEWS--then the username is the incorrect 3deedan785. I also noticed my ability to find older feedback postings are also username dependent. When I go to feedback my history is different depending on which username--3deedan or 3deedan785--I used to access it.
