Gangtok
The article Gangtok is in FAR. The main problem mentioned is lack of inline citations. We've added some citations. More should be added. Also, prose may need to be improved at places. Indeed, while adding inline citations from different sources, new materials sometimes come up and can be added, too.

I have gone through the sections history, geography, climate, economy, and, civic governance. History section probably needs some more materials as well as inline citations. You can help by adding citations and materials in any section you like to. A good source that we have come across is the City Development Plan of Gangtok City. This is a collection of PDF files full of info on the city. 

Thanks for asking. Yes, it would be great if you can manage some time and help improve the article, thereby saving it from demotion. Regards. (talk)
