I spent hours and hours on what not to see,
(To extend Ignored Users, specifically,)
So that it would work in last hour of cb
And then ambrus responded with simplicity.

I tried using javascript, with Greasemonkey installed,
For "editing scripts", it's normally called,
With testing and googling, i was enthralled,
Then a Perl Monks Discussion, to show what i scrawled.

But, .chatfrom_<some digits>, when i took a peek,
I mistakenly thought, was to keep it unique,
Corion explained, ambrus's critique,
It's the monk's node id, and not that oblique.

You work and you learn, even when it's for naught,
And look on with pride, when you see what you wrought,
Though the answer is different than i previously thought,
I'm happy i did it, i reached what i sought.
