Hi,
As you may or may not be aware, I'm coordinating the Philip Greenspun illustration project, whereby illustrators are paid to create desired illustrations for Wikimedia. http://meta.wikimedia.org/wiki/Philip_Greenspun_illustration_project
Round 1 is now underway. Part of the process is that when illustrators submit their created image, it is put in a "Review" stage before being finally accepted, so that people can comment on the quality and accuracy and improvements can be made.
Feedback is encouraged from anyone and can be made anonymously too. Images currently in review: http://ur1.ca/2g3 It's fairly similar to commenting on a Featured Picture nomination.
I want to have a small number of people with the designated role (in JIRA) of 'Reviewers'. These should be people that I trust to diligently check image accuracy, as best they can, against the illustrator's provided sources and other standard reference works. Reviewers will have the ability to change an image from being 'In review' to 'Accepted' (or alternately, 'Rejected', although I don't imagine that being used much). Reviewers also take into account generally provided feedback (which is why this is a very useful thing to do).
I have a few people but I need a few more. If you are interested in doing this please send me an email off-list.
thanks, Brianna
