I want to develop a classified ad posting site with wordpress like http://www.kijiji.ca/ . I have used different classified engine . But the problem is , in case of http://www.kijiji.ca/ first the user have to select a zone ,then then product category . Whenever user select a zone then user is redirect to a subdomain like sub.kijiji.ca . I want to implement the same thing with wordpress . I have created multi-site , but the problem the content of main site and sub domain remain different . Even users need signed up for every subdomain .
In this case what can I do , isn't it possible to do what I want?
Thanks in advance
