@fazalwahab11375, if the photography and for sale sections aren't getting views, it because people don't want them to be viewed. I don't understand why its necessary for those sections to get views.
I think it makes sense to merge photography with NWD, becuase you don't have threads people discussing the technical details of shots, asking how to frame pictures, etc. You just have picture sharing pictures (I'm guessing, never been there), and that's fine. You can, by and large, have one or two threads containing all the pictures.
Contrast that with ads; every new item requires a new thread. Thus the NWD is innundated with threads advertising items for sale.
I've actually stopped visiting NWD, because interesting content isn't immediately visible. And I'm not going to take the time and flip through a few pages until I find something interesting...
I find the enormous number of subdivision in Pakwheels often unnecessary and bizarre. I think the forums are incredibly fragmented and its nigh on impossible to get a cohesive picture of what's going on. But here in this instance, it absolutely makes sense to me to create a separate section for ads.
