There seems to be some bug in the en:Wiktionary's automatically generated list of categories. It continues to show (in red) categories that have been abandoned, and which have no text of their own. Editorial controversy about these categories is not an issue.
Is there any way that the category list can be periodically reviewed to remove the deadwood. While I understand that amending the list everytime there is a change could stress the system, a once-a-day purge would be helpful.
Thanks Ec
