I do not know how
From User talk:Αντιγόνη
User:Αντιγόνη! hello, sorry to bother you again. I need to add at Special:Categories a link to the valid Categories (I tried here, but you explained it should be done differently, locally.
This 'Special' page appears at the bottom of EVERY page and readers are complaining because it is full of red, unused Categories.
I know nothing about computers, and I see no way to get to edit the page Spedial:Categories, except from here. --Sarri.greek (talk) 09:02, 21 June 2019 (UTC)
