If you are using internet, that to some extent do mean that you have a facebook. That's how it is at present.

I see many people adding "Nepali" at the end of their name in Facebook to represent Nepal.

Do you use "Nepali" facebook covers also?

How many of you know about nepalifacebookcover.com ?

Do you create these covers yourself?

The things that people do to get some self promotion. Andyshrestha, facebook cover is about your own personal thing why would anyone want to use your cover? Your work is more suited for marketing websites not for personal.
