In my experience the best way to attract new members is to have a vibrant community...even if it consists of 3-4 people.. you have to show an edge that none other 1000s of desi forums have... something that adds extra value to this place..
I mean...your idea of having something for punjabi people is awsome..but you gotta work with it...get some top knotch music videos... have some flashy visual content for your front..have an awsome banner for the forum.. if you dont want any of my advise...atleast look through various competitors in this field.. that are offering a community platform for [[web 2.0]] experience.. to see what they have..and compare to what you are offering..

I hope my pep talk doesnt demotivate you...all I am saying is.. before you start searching for members and begging them to come to this place.. you have to make the place attractive enough for them.. =) No disrespect..
Best,
