English Challenge:

To get your message whitelisted, you have to answer the following question:

[A picture of ten cartoon elephants in four colours, red, green, blue and purple.]
[A picture of English text asking "How many green elephants are in the picture?"]

However, that doesn't work very well if you:

  1. are blind and using a screen-reader and speech synthesizer,
  2. are not blind but are using a text-only browser on a text-only system,
  3. are sending and receiving messages on a cell-phone with only email access and no web access,
  4. are sending email behind a company firewall that doesn't allow http access (to stop employees from surfing for porn),
  5. are colour-blind and can't tell green from red,
  6. are using a monochrome monitor and can't tell green from red,
