Similar to last month's event with the Weekend Testing group, this Saturday WMF is teaming with Openhatch.org for a "test event" to get critical eyeballs on the near-final version of the Article Feedback Tool before AFT gets rolled out to a wide audience in the very near future.
Like last time, we anticipate some Bugzilla issues being created for AFT on Saturday.
The test session is from 10AM-noon Pacific time.
