Well I've seen many sites, but I did not knew this one.
It is kindly inactive, so I think you need more propaganda, and more things on the files part, maybe somebody could make a tutorial on how modelling or skinning Wc3. So this place can be filled up.
So in other words: nobody visits the website, which leads to no real activity. No activity is there, which leads to no real changes on the website, and no changes on the website leads to less members (and with members I mean the active ones...)
Admins, you're trying to ressurect a dead guy..., because many websites are just better than yours in some ways. Anyway, don't lose the good things on your website if you make somekind of decision!
Well, maybe Wc3sear.ch is not the best example. But I think you need more things, for example in the modding part also you can include a modelling/skinning part, there are a lot of tutorials of that in other pages, and in fact I know how to do it, maybe I could make something like that?
