Effective today, the section of PerlMonks known as "Categorized Questions and Answers" is no longer in service. The section page is a tombstone. It is no longer possible to post Categorized Questions or Answers. It is also not possible to search such posts via Super Search. It wouldn't be useful anyway, because all of the posts which were Categorized Questions have been converted into SOPW posts. Likewise, all posts which were Categorized Answers have been converted into replies to those SOPW posts. In each case, the name of the CatQA 'section' in which the Question was placed has been added to the SOPW post as a keyword.
The intent of the CatQA section will, going forward, be fulfilled by a new system, whereby "good" questions (in SOPW) and their "best" answers will be given a special flag, as well as relevant keywords.
