How would one work out a Post/Get request URL to the "username change" action.

The url would be.
/usercp.php?action=changename

For example, to make
/usercp.php?action=changename&username=Deities
redirect to your browser's username change and the textbox to be filled in already.
(Like how it can work for Pm's by doing &message=blahblahblah)

You won't get around support denial by posting in a different forum.
