Admin Post Editing plugin for 1.6?

[katib]

I came across this plugin
http://mybbhacks.zingaburga.com/showthread.php?tid=157
which does:
# Post time
# Post user
# Post IP
# Remove Edited by line / Silent editing

But it is for 1.2
Doed it work for 1.6?
( I converted from phpbb3 and many posts converted as guest's posts, so I need to change post'author to its correct value )
