[Mediawiki-l] sequence to add a new user in mediawiki

Hi,

We want to disable Signup for new users in mediawiki and want to add them into database manually. for this we want to understand the sequence of function used to store a new user into mediawiki database. we looked this:- includes/GlobalFunctions.php

function wfEncryptPassword( $userid, $password ) { global $wgPasswordSalt; $p = md5( $password);

if($wgPasswordSalt) return md5( "{$userid}-{$p}" ); else return $p; }

But need to know that where $wgPasswordSalt set its value and finally where this function called to get encryted password.

Can you suggest sequence of storing a new user in mediawiki as this will be of great help.

Thank you
