I checked the categories... well, I'd like to add a category about "Animals" (first of all Buck, Chub, Sport and Cochise - the beautiful horses - then El Toro Grande, Old Sheba...) and a sub-category about "blind characters" (Gabrielle, Matthew Raine, Tessa Caldwell - though it's a temporary in the last case)... I found the button where I can add articles, but I didn't find the button/access to the button where I can edit the categories.
Again, could someone help me, please? =)
