VanHalenLover: What on earth would wgt need two copies of our profile for?
There are no "2 copies", of course. 
Just 2 URLs (addresses) pointing to the same webpage. A trivial and common thing on the Internet.
huh ???? 2 different addresses pointing to the same page, lol? They are in two unique directories, meaning they are two unique documents.
They are obviously using server-side scripting, hence the .aspx; but this still does not explain the two duplicate page builds. I'm wondering if they somehow lost track of using usernames, and are using a database conversion between the username and playerid, depending on where the link was initiated from.
