To create a related category, enter in the name you would like to appear (or leave blank for the default), and then click on the category you want to xxx to be related to.
I followed, but failed. The name@ still remains the original cat's name. How can I change it to an more appropriate name@? My version is 3.0.1.
Yeah I was having problems with that also. Put <%related%> somewhere on your page and it will show the name you put. The <%~loop related_loop%> is a bit weird as if you put it between that tages it shows up twice.
