Names of namespaces
If I understand correctly, "ਵਿਕਿਪੀਡਿਆ" is the word "Wikipedia" and it looks the same as in the logo. Do you want to change the name of the site? It is possible, but it is not done on translatewiki.net, and you should discuss it in the Community Portal of the Punjabi Wikipedia first.
Or are you talking about the "Wikipedia talk" namespace (ਵਿਕਿਪੀਡਿਆ ਚਰਚਾ)?
I'm talking about everywhere the word "wikipedia" is used in Punjabi as ਵਿਕਿਪੀਡਿਆ. It's spelled wrong and a users also pointed this out to me. There is also a namespace called "Wikipedia:" and of course "Wikipedia talk:" on every wiki, I first want to translate/correct the word for this namespace. For the site name I'll discuss it with the community, of course, and I'm sure they'll support me but please help for this namespace.
