Just a very small change I thought other people may be interested in, or have some comments on...
In the navbar on various pages, the "View Trader Ratings", "Edit Trader Ratings" etc link to the user you are currently editing - to fit in more with the traditional vB breadcrumbs style, these should perhaps link to the parent page, with no user specified.
Ideally, these would link to a page appropriate to the action in question, e.g. an edit/submit page where you can search for the user, but for something so simple and effective, that over complicates things rather - To simply have each link return to the trader ratings page, simply remove
PHP Code:
u=$userinfo[userid]
from each of the below lines in traderratings.php.
PHP Code:
$navbits = construct_navbits(array("traderratings.php?$session[sessionurl]u=$userinfo[userid]" => "View Trader Ratings",'' => $userinfo['username']));
$navbits = construct_navbits(array("traderratings.php?$session[sessionurl]u=$userinfo[userid]" => "Submit Trader Ratings Feedback",'' => $userinfo['username']));
$navbits = construct_navbits(array("traderratings.php?$session[sessionurl]u=$userinfo[userid]" => "Edit Trader Ratings Feedback",'' => $userinfo['username']));
