I am used to the fact that when 5 different users edit a question, that is automatically changed to a CW question.
Is this still valid? Does the number of editors include also the OP?
According to Meta Stack Overflow, the automatic triggers for CW conversion include:
- The body of the post has been edited by at least five (5) different users.
- The post has been edited ten (10) times by the original owner.
- The question generates more than 30 answers.
Rollbacks do not reverse any of the Community Wiki mode calculations.
(I don't know for sure that these numbers are valid for us on EL&U or still current.)
