I often edit / add to the wiki you're welcome to ask me questions if you ever need help.
This is a probably the best page to start reading:
http://wiki.project1999.com/Help:Contents
When making new pages I use this:
http://www.destinati.com/project1999wiki/wikiUtils.php
Words of warning. Always preview your edits/additions before you submit them. Take extra care in making sure you didn't miss a closing bracket or punctuation somewhere.
It is very easy to mess up an entire page if you simply forgot or accidentally removed something.
Feel free to PM me or leave a message on my discussion tab.

Be sure to leave a signature time stamp if you do so I know when your message was added. (There is a button at the top "Your signature with timestamp")
I also mention this button because if you edit or change a wiki page and you're unsure or think your addition is accurate. It's best to leave a message in the discussion section of that wiki page including your sig/timestamp.
Edit: I took a quick look at the
http://wiki.project1999.com/A_crystal_purifier page. looks fine to me. I did a look on alakazam and there is no entry for this mob. So you wont be able to use that neat tool for creating new pages I linked. You don't really have to worry about emu_id or illia_id to be honest.
