In the video on this page: https://premium.wpmudev.org/project/classifieds
it is mensioned: "with multi-site", you can create a whole network of localized classifieds site similar to craigslist".
How to do that? I mean, how to make classifieds that target for different cities to show on each different city?
For instance, there is a subsite for New York City, http://www.mydomain.com/nyc, and another subsite for LA, http://www.mydomain.com/la. How to set up the website to allow buddypress members to publish localized ads on a specified subsite? Subsite: http://www.mydomain.com/nyc only shows ads intended for New York City with various categories.
