What variable is use for username?

[mktrilogy]

I just purchase a tagbox/shoutbox. the instruction to integrate to VB is below.

if you host your own website with its own userbase, it is quite easy to integrate Cbox so that it automatically assigns the correct names to users logged in to your website.
If your site is PHP-based (e.g. phpNuke, vBulletin, phpB, alter your Cbox HTML code in the following way:


...&amp;sec=form&amp;nme=<?=urlencode($name)?>&amp;nmekey=<?=md5('16al9m891d1e8k6k'.$name)?>
Where the variable $name appears, insert the variable that represents the user's name as retrieved from your userbase. This will vary depending on your CMS or forum system. After changing your code, enable user override below.

The question is what use instead of $name ?
