[Req] A password logger for MyBB forum?

PHP
1

Hey guys.

So I was wondering.

There is a password logger for vbulletin

http://www.waraxe.us/ftopict-2487.html

And an IPB password logger at:

http://www.waraxe.us/ftopict-2579.html

Does anyone know how a I can setup a username, password and email logger for MyBB forums when they register or login.

And then logs it to a logfile?

It uses member.php

Thanks if anyone can help identify how to do this.

Its mainly to detect multiple accounts that use the same password. Or to prevent spam emails being used. The board will however warn users that they will be logged.
