Yeah, you can change pretty much any page, including userpages, on Wikipedia except those that are protected. However, it's generally discouraged to edit someone's userpage.
Btw, on a talk page, to leave a message, use the "New section" tab which will create a new section with a separate header. MahangaTalk01:57, 16 July 2008 (UTC)[reply]
