My E-mail box fills up so fast with SPAM from random
URLs from spammers who have learned that spelling
"penis" as "p-e-n-i-s" or "p-e+n=i-s" (and other words
similarly spelled) get past a lot of SPAM blockers.
This is why *I'm* considering SPAM blockers. And I
suspect that government agencies (such as the ones I
was referring to in this message) need to reduce SPAM
drastically to cut their costs so Dubya can afford to...but
I'll leave politics out of this for now.

I *knew* that, and the context of the sentence I posted made my knowledge
*very clear*. The *entire* sentence you replied to was (and note
highlighted portion):

*Government agencies* choosing to use challenge-response systems which
use pictures of numbers. Not for-profit corporations, not independent
non-profits, *government agencies*.

Cool. I'll download the newest version and check it out.
(with any luck the features didn't change from 1.4 to 1.6 like I noticed,
from *personal experience*, the change from 1.2 to 1.3).
