::Didn't see the relevance of including all productions at the entertainment venues unless they pass some sort of notability threshold. In my opinion, No Mercy (20070 didn't pass my threshold.  However, it seems to have passed yours.  I don't see the need to bring all productions within the scope of our Project. For instance, do we really want Haunted Hollow or Winter Wonderland from upcoming Toyota Park events?  The threshold will always be subjective and so we will need to come up with a way to isolate the important ones from the frivolous. Hopefully editors will limit bringing all productions within the scope of our Project. My plans are to continue with documenting the category process ( at Wikipedia:WikiProject Chicago/Categories as it is now and then make changes.  Test changes will be done along the way.  So, I'll create a category category:Entertainment events Chicago, Illinois and  category:Entertainment events in Chicago metro area, Illinois.
