 * Symbol confirmed.svg New enough, long enough, good in-line references to a variety of reliable sources. Hook is interesting and short enough. Reviewed required one article. -AndrewDressel (talk) 14:32, 27 May 2013 (UTC)


 * Symbol question.svg The Copyvio check tool always returns "Error ! AttributeError: 'NoneType' object has no attribute 'find_all'" -AndrewDressel (talk) 14:32, 27 May 2013 (UTC)
 * AndrewDressel, Copyvio is located at Toolserver, which has been going down habitually the last few months. It's not about DYK. Please post this at Village pump (technical).  Dup Detector above is located at Labs, and is in working order, and accomplishes the same thing except you have to do it by each individual reference. — Maile  (talk) 20:22, 27 May 2013 (UTC)


 * Symbol confirmed.svg The Copyvio check tool is working now and reports only a "3.5% confidence of a violation," and that is based only on a few phrases, such as "his master's degree in mathematics", matching a source, but when describing some other author, so I cannot see how it could be an issue. -AndrewDressel (talk) 13:28, 28 May 2013 (UTC)
