Empty categories in World: Chinese Traditional: 電腦: 網際網路: 網頁服務

Hello,
I have found some empty categoeries in World: Chinese Traditional: 電腦: 網際網路: 網頁服務

I think those sub-categories (0,3,A,B....) are all unnecessary and should be deleted. What do you think?

Thanks
Pang

Is this the category ?

Yes, that is the category I am talking.

I think at some time, there were sites in these categories, but as time goes, some sites might be deleted or moved, so left the categories empty.
At this time, as there are not too many sites in this category, so those sub-categories indeed unnecessary, I asked other editors to see how to deal this matter.
