On Friday 10th August there will be a 2 hour experiment in which pages from devices that are unusual (for some definition of this, which might just be "not Chrome on Windows") we will show a CAPTCHA to solve.
The test will only run for 2 hours, few people should see the CAPTCHA, and it should help get a new capability that will protect the site.
Since people will look here, an advance warning.
