How nice fckxoops is!

I would like to permit uploads from reliable users.
Are there any problems in the following changes in config_and_auth.inc.php?

1. The upload directory for a user is assigned as

if( $xoopsUser->getVar('rank') == 7) {
define( 'FCK_UPLOAD_PATH' , XOOPS_UPLOAD_PATH.'/fckeditor');
define( 'FCK_UPLOAD_URL' , XOOPS_UPLOAD_URL.'/fckeditor');
} else {
define( 'FCK_UPLOAD_PATH' , XOOPS_UPLOAD_PATH.'/fckeditor' . '/' . $xoopsUser->uname()) ;
define( 'FCK_UPLOAD_URL' , XOOPS_UPLOAD_URL.'/fckeditor' . '/' . $xoopsUser->uname()) ;
}

2. We lower the authentication level to rank=1.

We also would like to add delete & rename functionalities and implement thumbnail images such as http://www.mcpuk.net/fbxp/.
What do you think?
