Category talk:Weaponsmiths

Can't figure out how to add (edit) the Weaponsmiths (Eye of the North) link and a big E over it in the subcategory section :/

This is the page I'm trying to get linked in there http://gw.gamewikis.org/wiki/Weaponsmiths_%28Eye_of_the_North%29

Could not find any help on that in the help section. User:Imaginos
