Editing most Wikipedia pages is simple. Simply click on the "edit" tab at the top of a Wikipedia page (or on a section-edit link). This will bring you to a new page with a text box containing the editable text of the current page.
upcScavenger is a wiki, meaning that anyone can edit any unprotected page and improve articles immediately for all readers. You do not need to register to do this. Anyone who has edited is known as a "Wikipedian" and, no matter how trivial the edit may seem, can be proud that he or she has helped make Wikipedia what it is. All of these edits add up!
