[wplug-plan] reCaptcha for preventing spam

[Patrick Wagstrom]

If you look at the wiki today, you'll see that I just had to kill a 
pretty decent amount of spam.  That sucks.  I hate spam.  It makes our 
wiki less valuable and takes personal time to get rid of the spam.

As you may have heard, Luis von Ahn, Carnegie Mellon's resident genius 
and the developer of the captcha, has recently released the recaptcha 
project.  Basically, with this project, you solve two captchas, one a 
real captcha, and one a word that OCR couldn't get from some book from 
the internet archive.  After it reaches consensus on the second word it 
concludes that must be the word and the book gets better.

Plus, it's got a dead sexy interface and wonderful plugins for lots of 
platforms, including MediaWiki.  I suggest that we utilize the recaptcha 
project for the wiki.  Heck, I'll even install it if someone gives me 
access rights to it.
