Sorting Member List's by Custom Fields

[meissenation]

Hi Guys,

On my forum, I've added some of my custom fields to the member list such as their Title being a seperate column for example. I'd like to organize the memberlist (by default) according to their Title in DESC order. I'm figuring this requires editing the core memberlist.php file, which I've looked through but can't quite decipher where I need to edit. I know I can't post the whole file or the entire code up, but I'm hoping I can find some help on this. I vaguely remember writing PHP code for PHP Nuke to sort via mySql query commands when it creates an array, but alas I'm not sure how it's done via the more powerful vBulletin, and I'm no programmer. Anyone know how to do this or what code to edit?

Thanks in advance,
Brian

I tried asking at vbulletin.com but they won't offer help on editing code, funny when they'd be the ones most comfortable navigating their own code. Anyone?
