On April 23 to hcoop-discuss, msgid
20110423043444.GL28984 at boltzmann.zgib.net, I sent my textcha code.  It
just says "please enter this number backwards".  At that time, bots
were also creating user accounts on my wiki.  This textcha has reduced
spam to basically zero in the year or so since then, so I recommend
something like this, as it is so easy.

If you want custom questions: 

   textchas = {'en': 
               {'enter the letter "a"': 'a',
                'how many legs does a camel have?': '4|four',
                'what is the opposite of "left"?': 'right',
               }
              }

I will add these to the wiki.  If you have opinions on what questions
to use, please let me know.
